E | Page 4 of 60 | July 2009 ALU SHIFTER MULTIPLIER MSB 80-BIT MSF 80-BIT ADSP-21367/ADSP-21368/ADSP-21369 SIMD Computational Engine The processors contain two computational processing elements that operate as a single-instruction, multiple-data (SIMD) engine. The processing elements are referred to as PEX and PEY and each contains an ALU, multiplier, shifter, and register file. PEX is always active, and PEY may be enabled by setting the PEYEN mode bit in the MODE1 register. When this mode is enabled, the same instruction is executed in both processing elements, but each processing element operates on different data. This architecture is efficient at executing math intensive DSP algorithms. Entering SIMD mode also has an effect on the way data is transferred between memory and the processing elements. When in SIMD mode, twice the data bandwidth is required to sustain computational operation in the processing elements. Because of this requirement, entering SIMD mode also doubles the bandwidth between memory and the processing elements. When using the DAGs to transfer data in SIMD mode, two data values are transferred with each access of memory or the register file. The data bus exchange register (PX) permits data to be passed between the 64-bit PM data bus and the 64-bit DM data bus, or between the 40-bit register file and the PM data bus. These registers contain hardware to handle the data width difference. Timer A core timer that can generate periodic software Interrupts. The core timer can be configured to use FLAG3 as a timer expired signal Single-Cycle Fetch of Instruction and Four Operands The ADSP-21367/ADSP-21368/ADSP-21369 feature an enhanced Harvard architecture in which the data memory (DM) bus transfers data and the program memory (PM) bus transfers both instructions and data (see Figure 2 on Page 4). With separate program and data memory buses and on-chip instruction cache, the processors can simultaneously fetch four operands (two over each data bus) and one instruction (from the cache), all in a single cycle. Instruction Cache Independent, Parallel Computation Units Within each processing element is a set of computational units. The computational units consist of an arithmetic/logic unit (ALU), multiplier, and shifter. These units perform all operations in a single cycle. The three units within each processing element are arranged in parallel, maximizing computational throughput. Single multifunction instructions execute parallel ALU and multiplier operations. In SIMD mode, the parallel ALU and multiplier operations occur in both processing elements. These computation units support IEEE 32-bit singleprecision floating-point, 40-bit extended precision floatingpoint, and 32-bit fixed-point data formats. Data Register File A general-purpose data register file is contained in each processing element. The register files transfer data between the computation units and the data buses, and store intermediate results. These 10-port, 32-register (16 primary, 16 secondary) register files, combined with the ADSP-2136x enhanced Harvard architecture, allow unconstrained data flow between computation units and internal memory. The registers in PEX are referred to as R0-R15 and in PEY as S0-S15. Context Switch The processors include an on-chip instruction cache that enables three-bus operation for fetching an instruction and four data values. The cache is selective--only the instructions whose fetches conflict with PM bus data accesses are cached. This cache allows full-speed execution of core, looped operations such as digital filter multiply-accumulates, and FFT butterfly processing. Data Address Generators with Zero-Overhead Hardware Circular Buffer Support The ADSP-21367/ADSP-21368/ADSP-21369 have two data address generators (DAGs). The DAGs are used for indirect addressing and implementing circular data buffers in hardware. Circular buffers allow efficient programming of delay lines and other data structures required in digital signal processing, and are commonly used in digital filters and Fourier transforms. The two DAGs contain sufficient registers to allow the creation of up to 32 circular buffers (16 primary register sets, 16 secondary). The DAGs automatically handle address pointer wraparound, reduce overhead, increase performance, and simplify implementation. Circular buffers can start and end at any memory location. Flexible Instruction Set Many of the processor's registers have secondary registers that can be activated during interrupt servicing for a fast context switch. The data registers in the register file, the DAG registers, and the multiplier result registers all have secondary registers. The primary registers are active at reset, while the secondary registers are activated by control bits in a mode control register. Universal Registers The 48-bit instruction word accommodates a variety of parallel operations for concise programming. For example, the ADSP-21367/ADSP-21368/ADSP-21369 can conditionally execute a multiply, an add, and a subtract in both processing elements while branching and fetching up to four 32-bit values from memory--all in a single instruction. On-Chip Memory These registers can be used for general-purpose tasks. The USTAT (4) registers allow easy bit manipulations (Set, Clear, Toggle, Test, XOR) for all system registers (control/status) of the core. Rev. E The processors contain two megabits of internal RAM and six megabits of internal mask-programmable ROM. Each block can be configured for different combinations of code and data storage (see Table 3 on Page 6). Each memory block supports single-cycle, independent accesses by the core processor and I/O | Page 5 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 processor. The memory architecture, in combination with its separate on-chip buses, allows two data transfers from the core and one from the I/O processor, in a single cycle. Table 3.

Please contact your Analog Devices sales representative for additional details. The SRAM can be configured as a maximum of 64k words of 32-bit data, 128k words of 16-bit data, 42k words of 48-bit instructions (or 40-bit data), or combinations of different word sizes up to two megabits. All of the memory can be accessed as 16-bit, 32-bit, 48-bit, or 64-bit words. A 16-bit floating-point storage format is supported that effectively doubles the amount of data that can be stored on-chip. Conversion between the 32-bit floating-point and 16-bit floating-point formats is performed in a single instruction. While each memory block can store combinations of code and data, accesses are most efficient when one block stores data using the DM bus for transfers, and the other block stores instructions and data using the PM bus for transfers. Using the DM bus and PM buses, with one bus dedicated to each memory block, assures single-cycle execution with two data transfers. In this case, the instruction must be available in the cache. Rev. E On-Chip Memory Bandwidth The internal memory architecture allows programs to have four accesses at the same time to any of the four blocks (assuming there are no block conflicts). The total bandwidth is realized using the DMD and PMD buses (2x64-bits, core CLK) and the IOD0/1 buses (2x32-bit, PCLK). ROM-Based Security The ADSP-21367/ADSP-21368/ADSP-21369 have a ROM security feature that provides hardware support for securing user software code by preventing unauthorized reading from the internal code when enabled. When using this feature, the processor does not boot-load any external code, executing exclusively from internal ROM. Additionally, the processor is not freely accessible via the JTAG port. Instead, a unique 64-bit key, which must be scanned in through the JTAG or test access port will be assigned to each customer. The device will ignore a wrong key. Emulation features and external boot modes are only available after the correct key is scanned. | Page 6 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 FAMILY PERIPHERAL ARCHITECTURE Table 4. External Memory for SDRAM Addresses The ADSP-21367/ADSP-21368/ADSP-21369 family contains a rich set of peripherals that support a wide variety of applications including high quality audio, medical imaging, communications, military, test equipment, 3D graphics, speech recognition, motor control, imaging, and other applications. Bank Size in Words Address Range Bank 0 62M 0x0020 0000-0x03FF FFFF Bank 1 64M 0x0400 0000-0x07FF FFFF External Port Bank 2 64M 0x0800 0000-0x0BFF FFFF The external port interface supports access to the external memory through core and DMA accesses. The external memory address space is divided into four banks. Any bank can be programmed as either asynchronous or synchronous memory. The external ports of the ADSP-21367/8/9 processors are comprised of the following modules. Bank 3 64M 0x0C00 0000-0x0FFF FFFF * An Asynchronous Memory Interface which communicates with SRAM, FLASH, and other devices that meet the standard asynchronous SRAM access protocol. The AMI supports 14M words of external memory in bank 0 and 16M words of external memory in bank 1, bank 2, and bank 3. * An SDRAM controller that supports a glueless interface with any of the standard SDRAMs. The SDC supports 62M words of external memory in bank 0, and 64M words of external memory in bank 1, bank 2, and bank 3. * Arbitration Logic to coordinate core and DMA transfers between internal and external memory over the external port. * A Shared Memory Interface that allows the connection of up to four ADSP-21368 processors to create shared external bus systems (ADSP-21368 only). SDRAM Controller The SDRAM controller provides an interface of up to four separate banks of industry-standard SDRAM devices or DIMMs, at speeds up to fSCLK. Fully compliant with the SDRAM standard, each bank has its own memory select line (MS0-MS3), and can be configured to contain between 16M bytes and 128M bytes of memory. SDRAM external memory address space is shown in Table 4. A set of programmable timing parameters is available to configure the SDRAM banks to support slower memory devices. The memory banks can be configured as either 32 bits wide for maximum performance and bandwidth or 16 bits wide for minimum device count and lower system cost. The SDRAM controller address, data, clock, and control pins can drive loads up to distributed 30 pF loads. For larger memory systems, the SDRAM controller external buffer timing should be selected and external buffering should be provided so that the load on the SDRAM controller pins does not exceed 30 pF. External Memory The external port provides a high performance, glueless interface to a wide variety of industry-standard memory devices. The 32-bit wide bus can be used to interface to synchronous and/or asynchronous memory devices through the use of its separate internal memory controllers. The first is an SDRAM controller Rev. E for connection of industry-standard synchronous DRAM devices and DIMMs (dual inline memory module), while the second is an asynchronous memory controller intended to interface to a variety of memory devices. Four memory select pins enable up to four separate devices to coexist, supporting any desired combination of synchronous and asynchronous device types. Non-SDRAM external memory address space is shown in Table 5. Table 5. External Memory for Non-SDRAM Addresses Bank Size in Words Address Range Bank 0 14M 0x0020 0000-0x00FF FFFF Bank 1 16M 0x0400 0000-0x04FF FFFF Bank 2 16M 0x0800 0000-0x08FF FFFF Bank 3 16M 0x0C00 0000-0x0CFF FFFF Shared External Memory The ADSP-21368 processor supports connecting to common shared external memory with other ADSP-21368 processors to create shared external bus processor systems. This support includes: * Distributed, on-chip arbitration for the shared external bus * Fixed and rotating priority bus arbitration * Bus time-out logic * Bus lock Multiple processors can share the external bus with no additional arbitration logic. Arbitration logic is included on-chip to allow the connection of up to four processors. Bus arbitration is accomplished through the BR1-4 signals and the priority scheme for bus arbitration is determined by the setting of the RPBA pin. Table 8 on Page 13 provides descriptions of the pins used in multiprocessor systems. External Port Throughput The throughput for the external port, based on 166 MHz clock and 32-bit data bus, is 221M bytes/s for the AMI and 664M bytes/s for SDRAM. | Page 7 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 Asynchronous Memory Controller The asynchronous memory controller provides a configurable interface for up to four separate banks of memory or I/O devices. Each bank can be independently programmed with different timing parameters, enabling connection to a wide variety of memory devices including SRAM, ROM, flash, and EPROM, as well as I/O devices that interface with standard memory control lines. Bank 0 occupies a 14M word window and Banks 1, 2, and 3 occupy a 16M word window in the processor's address space but, if not fully populated, these windows are not made contiguous by the memory controller logic. The banks can also be configured as 8-bit, 16-bit, or 32-bit wide buses for ease of interfacing to a range of memories and I/O devices tailored either to high performance or to low cost and power. Pulse-Width Modulation The PWM module is a flexible, programmable, PWM waveform generator that can be programmed to generate the required switching patterns for various applications related to motor and engine control or audio power control. The PWM generator can generate either center-aligned or edge-aligned PWM waveforms. In addition, it can generate complementary signals on two outputs in paired mode or independent signals in nonpaired mode (applicable to a single group of four PWM waveforms). The entire PWM module has four groups of four PWM outputs each. Therefore, this module generates 16 PWM outputs in total. Each PWM group produces two pairs of PWM signals on the four PWM outputs. The PWM generator is capable of operating in two distinct modes while generating center-aligned PWM waveforms: single update mode or double update mode. In single update mode, the duty cycle values are programmable only once per PWM period. This results in PWM patterns that are symmetrical about the midpoint of the PWM period. In double update mode, a second updating of the PWM registers is implemented at the midpoint of the PWM period. In this mode, it is possible to produce asymmetrical PWM patterns that produce lower harmonic distortion in 2-phase PWM inverters. Digital Applications Interface (DAI) The digital applications interface (DAI ) provide the ability to connect various peripherals to any of the DSP's DAI pins (DAI_P20-1). Programs make these connections using the signal routing unit (SRU1), shown in Figure 1. The SRU is amatrix routing unit (or group of multiplexers) that enable the peripherals provided by the DAI to be interconnected under software control. This allows easy use of the associated peripherals for a much wider variety of applications by using a larger set of algorithms than is possible with nonconfigurable signal paths. The DAI include eight serial ports, an S/PDIF receiver/transmitter, four precision clock generators (PCG), eight channels of synchronous sample rate converters, and an input data port (IDP). The IDP provides an additional input path to the Rev. E processor core, configurable as either eight channels of I2S serial data or as seven channels plus a single 20-bit wide synchronous parallel data acquisition port. Each data channel has its own DMA channel that is independent from the processor's serial ports. For complete information on using the DAI, see the ADSP-21368 SHARC Processor Hardware Reference. Serial Ports The processors feature eight synchronous serial ports (SPORTs) that provide an inexpensive interface to a wide variety of digital and mixed-signal peripheral devices such as Analog Devices' AD183x family of audio codecs, ADCs, and DACs. The serial ports are made up of two data lines, a clock, and frame sync. The data lines can be programmed to either transmit or receive and each data line has a dedicated DMA channel. Serial ports are enabled via 16 programmable and simultaneous receive or transmit pins that support up to 32 transmit or 32 receive channels of audio data when all eight SPORTs are enabled, or eight full duplex TDM streams of 128 channels per frame. The serial ports operate at a maximum data rate of 50 Mbps. Serial port data can be automatically transferred to and from on-chip memory via dedicated DMA channels. Each of the serial ports can work in conjunction with another serial port to provide TDM support. One SPORT provides two transmit signals while the other SPORT provides the two receive signals. The frame sync and clock are shared. Serial ports operate in five modes: * Standard DSP serial mode * Multichannel (TDM) mode with support for packed I2S mode * I2S mode * Packed I2S mode * Left-justified sample pair mode Left-justified sample pair mode is a mode where in each frame sync cycle two samples of data are transmitted/received--one sample on the high segment of the frame sync, the other on the low segment of the frame sync. Programs have control over various attributes of this mode. Each of the serial ports supports the left-justified sample pair and I2S protocols (I2S is an industry-standard interface commonly used by audio codecs, ADCs, and DACs such as the Analog Devices AD183x family), with two data pins, allowing four left-justified sample pair or I2S channels (using two stereo devices) per serial port, with a maximum of up to 32 I2S channels. The serial ports permit little-endian or big-endian transmission formats and word lengths selectable from 3 bits to 32 bits. For the left-justified sample pair and I2S modes, dataword lengths are selectable between 8 bits and 32 bits. Serial ports offer selectable synchronization and transmit modes as well as optional -law or A-law companding selection on a per channel basis. Serial port clocks and frame syncs can be internally or externally generated. | Page 8 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 The serial ports also contain frame sync error detection logic where the serial ports detect frame syncs that arrive early (for example, frame syncs that arrive while the transmission/reception of the previous word is occurring). All the serial ports also share one dedicated error interrupt. S/PDIF-Compatible Digital Audio Receiver/Transmitter The S/PDIF receiver/transmitter has no separate DMA channels. It receives audio data in serial format and converts it into a biphase encoded signal. The serial data input to the receiver/transmitter can be formatted as left-justified, I2S, or right-justified with word widths of 16, 18, 20, or 24 bits. The serial data, clock, and frame sync inputs to the S/PDIF receiver/transmitter are routed through the signal routing unit (SRU). They can come from a variety of sources such as the SPORTs, external pins, the precision clock generators (PCGs), or the sample rate converters (SRC) and are controlled by the SRU control registers. Synchronous/Asynchronous Sample Rate Converter The sample rate converter (SRC) contains four SRC blocks and is the same core as that used in the AD1896 192 kHz stereo asynchronous sample rate converter and provides up to 128 dB SNR. The SRC block is used to perform synchronous or asynchronous sample rate conversion across independent stereo channels, without using internal processor resources. The four SRC blocks can also be configured to operate together to convert multichannel audio data without phase mismatches. Finally, the SRC can be used to clean up audio data from jittery clock sources such as the S/PDIF receiver. Input Data Port The IDP provides up to eight serial input channels--each with its own clock, frame sync, and data inputs. The eight channels are automatically multiplexed into a single 32-bit by eight-deep FIFO. Data is always formatted as a 64-bit frame and divided into two 32-bit words. The serial protocol is designed to receive audio channels in I2S, left-justified sample pair, or right-justified mode. One frame sync cycle indicates one 64-bit left/right pair, but data is sent to the FIFO as 32-bit words (that is, onehalf of a frame at a time). The processor supports 24- and 32-bit I2S, 24- and 32-bit left-justified, and 24-, 20-, 18- and 16-bit right-justified formats. Precision Clock Generators The precision clock generators (PCG) consist of four units, each of which generates a pair of signals (clock and frame sync) derived from a clock input signal. The units, A B, C, and D, are identical in functionality and operate independently of each other. The two signals generated by each unit are normally used as a serial bit clock/frame sync pair. Digital Peripheral Interface (DPI) The digital peripheral interface provides connections to two serial peripheral interface ports (SPI), two universal asynchronous receiver-transmitters (UARTs), a 2-wire interface (TWI), 12 flags, and three general-purpose timers. Rev. E Serial Peripheral (Compatible) Interface The processors contain two serial peripheral interface ports (SPIs). The SPI is an industry-standard synchronous serial link, enabling the SPI-compatible port to communicate with other SPI-compatible devices. The SPI consists of two data pins, one device select pin, and one clock pin. It is a full-duplex synchronous serial interface, supporting both master and slave modes. The SPI port can operate in a multimaster environment by interfacing with up to four other SPI-compatible devices, either acting as a master or slave device. The ADSP-21367/ ADSP-21368/ADSP-21369 SPI-compatible peripheral implementation also features programmable baud rate and clock phase and polarities. The SPI-compatible port uses open-drain drivers to support a multimaster configuration and to avoid data contention. UART Port The processors provide a full-duplex universal asynchronous receiver/transmitter (UART) port, which is fully compatible with PC-standard UARTs. The UART port provides a simplified UART interface to other peripherals or hosts, supporting full-duplex, DMA-supported, asynchronous transfers of serial data. The UART also has multiprocessor communication capability using 9-bit address detection. This allows it to be used in multidrop networks through the RS-485 data interface standard. The UART port also includes support for five data bits to eight data bits, one stop bit or two stop bits, and none, even, or odd parity. The UART port supports two modes of operation: * PIO (programmed I/O) - The processor sends or receives data by writing or reading I/O-mapped UART registers. The data is double-buffered on both transmit and receive. * DMA (direct memory access) - The DMA controller transfers both transmit and receive data. This reduces the number and frequency of interrupts required to transfer data to and from memory. The UART has two dedicated DMA channels, one for transmit and one for receive. These DMA channels have lower default priority than most DMA channels because of their relatively low service rates. The UART port's baud rate, serial data format, error code generation and status, and interrupts are programmable: * Supporting bit rates ranging from (fSCLK/1,048,576) to (fSCLK/16) bits per second. * Supporting data formats from 7 bits to 12 bits per frame. * Both transmit and receive operations can be configured to generate maskable interrupts to the processor. Where the 16-bit UART_Divisor comes from the DLH register (most significant eight bits) and DLL register (least significant eight bits). In conjunction with the general-purpose timer functions, autobaud detection is supported. | Page 9 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 Peripheral Timers Delay Line DMA Three general-purpose timers can generate periodic interrupts and be independently set to operate in one of three modes: The ADSP-21367/ADSP-21368/ADSP-21369 processors provide delay line DMA functionality. This allows processor reads and writes to external delay line buffers (in external memory, SRAM, or SDRAM) with limited core interaction. * Pulse waveform generation mode * Pulse width count/capture mode SYSTEM DESIGN * External event watchdog mode Each general-purpose timer has one bidirectional pin and four registers that implement its mode of operation: a 6-bit configuration register, a 32-bit count register, a 32-bit period register, and a 32-bit pulse width register. A single control and status register enables or disables all three general-purpose timers independently. 2-Wire Interface Port (TWI) The TWI is a bidirectional 2-wire serial bus used to move 8-bit data while maintaining compliance with the I2C bus protocol. The TWI master incorporates the following features: * Simultaneous master and slave operation on multiple device systems with support for multimaster data arbitration The following sections provide an introduction to system design options and power supply issues. Program Booting The internal memory of the processors can be booted up at system power-up from an 8-bit EPROM via the external port, an SPI master or slave, or an internal boot. Booting is determined by the boot configuration (BOOT_CFG1-0) pins (see Table 7 and the processor hardware reference). Selection of the boot source is controlled via the SPI as either a master or slave device, or it can immediately begin executing from ROM. Table 7. Boot Mode Selection BOOT_CFG1-0 00 01 10 11 * Digital filtering and timed event processing * 7-bit and 10-bit addressing * 100 kbps and 400 kbps data rates * Low interrupt rate Booting Mode SPI Slave Boot SPI Master Boot EPROM/FLASH Boot Reserved I/O PROCESSOR FEATURES Power Supplies The I/O processor provides many channels of DMA, and controls the extensive set of peripherals described in the previous sections. The processors have separate power supply connections for the internal (VDDINT), external (VDDEXT), and analog (AVDD/AVSS) power supplies. The internal and analog supplies must meet the 1.3 V requirement for the 400 MHz device and 1.2 V for the 333 MHz and 266 MHz devices. The external supply must meet the 3.3 V requirement. All external supply pins must be connected to the same power supply. DMA Controller The processor's on-chip DMA controller allows data transfers without processor intervention. The DMA controller operates independently and invisibly to the processor core, allowing DMA operations to occur while the core is simultaneously executing its program instructions. DMA transfers can occur between the processor's internal memory and its serial ports, the SPI-compatible (serial peripheral interface) ports, the IDP (input data port), the parallel data acquisition port (PDAP), or the UART. Thirty four channels of DMA are available on the ADSP-2136x processors as shown in Table 6. Table 6. DMA Channels Peripheral SPORTs PDAP SPI UART External Port Memory-to-Memory DMA Channels 16 8 2 4 2 2 Rev. E Note that the analog supply pin (AVDD) powers the processor's internal clock generator PLL. To produce a stable clock, it is recommended that PCB designs use an external filter circuit for the AVDD pin. Place the filter components as close as possible to the AVDD/AVSS pins. For an example circuit, see Figure 3. (A recommended ferrite chip is the muRata BLM18AG102SN1D). To reduce noise coupling, the PCB should use a parallel pair of power and ground planes for VDDINT and GND. Use wide traces to connect the bypass capacitors to the analog power (AVDD) and ground (AVSS) pins. Note that the AVDD and AVSS pins specified in Figure 3 are inputs to the processor and not the analog ground plane on the board--the AVSS pin should connect directly to digital ground (GND) at the chip. | Page 10 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 100nF 10nF 1nF ADSP-213xx AVDD VDDINT HI-Z FERRITE BEAD CHIP developer can identify bottlenecks in software quickly and efficiently. By using the profiler, the programmer can focus on those areas in the program that impact performance and take corrective action. Debugging both C/C++ and assembly programs with the VisualDSP++ debugger, programmers can: AVSS * View mixed C/C++ and assembly code (interleaved source and object information) LOCATE ALL COMPONENTS CLOSE TO AVDD AND AVSS PINS * Insert breakpoints * Set conditional breakpoints on registers, memory, and stacks Figure 3. Analog Power (AVDD) Filter Circuit Target Board JTAG Emulator Connector * Perform linear or statistical profiling of program execution Analog Devices DSP Tools product line of JTAG emulators uses the IEEE 1149.1 JTAG test access port of the ADSP-21367/ ADSP-21368/ADSP-21369 processors to monitor and control the target board processor during emulation. Analog Devices DSP Tools product line of JTAG emulators provides emulation at full processor speed, allowing inspection and modification of memory, registers, and processor stacks. The processor's JTAG interface ensures that the emulator will not affect target system loading or timing. * Fill, dump, and graphically plot the contents of memory For complete information on Analog Devices' SHARC DSP Tools product line of JTAG emulator operation, see the appropriate "Emulator Hardware User's Guide." DEVELOPMENT TOOLS The processors are supported with a complete set of CROSSCORE(R) software and hardware development tools, including Analog Devices emulators and VisualDSP++(R) development environment. The same emulator hardware that supports other SHARC processors also fully emulates the ADSP-21367/ ADSP-21368/ADSP-21369. The VisualDSP++ project management environment lets programmers develop and debug an application. This environment includes an easy to use assembler (which is based on an algebraic syntax), an archiver (librarian/library builder), a linker, a loader, a cycle-accurate instruction-level simulator, a C/C++ compiler, and a C/C++ runtime library that includes DSP and mathematical functions. A key point for these tools is C/C++ code efficiency. The compiler has been developed for efficient translation of C/C++ code to DSP assembly. The SHARC has architectural features that improve the efficiency of compiled C/C++ code. The VisualDSP++ debugger has a number of important features. Data visualization is enhanced by a plotting package that offers a significant level of flexibility. This graphical representation of user data enables the programmer to quickly determine the performance of an algorithm. As algorithms grow in complexity, this capability can have increasing significance on the designer's development schedule, increasing productivity. Statistical profiling enables the programmer to nonintrusively poll the processor as it is running the program. This feature, unique to VisualDSP++, enables the software developer to passively gather important code execution metrics without interrupting the real-time characteristics of the program. Essentially, the Rev. E * Perform source level debugging * Create custom debugger windows The VisualDSP++ IDDE lets programmers define and manage DSP software development. Its dialog boxes and property pages let programmers configure and manage all of the SHARC development tools, including the color syntax highlighting in the VisualDSP++ editor. This capability permits programmers to: * Control how the development tools process inputs and generate outputs * Maintain a one-to-one correspondence with the tool's command line switches The VisualDSP++ Kernel (VDK) incorporates scheduling and resource management tailored specifically to address the memory and timing constraints of DSP programming. These capabilities enable engineers to develop code more effectively, eliminating the need to start from the very beginning, when developing new application code. The VDK features include threads, critical and unscheduled regions, semaphores, events, and device flags. The VDK also supports priority-based, preemptive, cooperative, and time-sliced scheduling approaches. In addition, the VDK was designed to be scalable. If the application does not use a specific feature, the support code for that feature is excluded from the target system. Because the VDK is a library, a developer can decide whether to use it or not. The VDK is integrated into the VisualDSP++ development environment, but can also be used via standard command line tools. When the VDK is used, the development environment assists the developer with many error-prone tasks and assists in managing system resources, automating the generation of various VDK-based objects, and visualizing the system state, when debugging an application that uses the VDK. Use the Expert Linker to visually manipulate the placement of code and data on the embedded system. View memory utilization in a color-coded graphical form, easily move code and data to different areas of the processor or external memory with a drag of the mouse and examine runtime stack and heap usage. The expert linker is fully compatible with the existing linker definition file (LDF), allowing the developer to move between the graphical and textual environments. | Page 11 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 In addition to the software and hardware development tools available from Analog Devices, third parties provide a wide range of tools supporting the SHARC processor family. Hardware tools include SHARC processor PC plug-in cards. Thirdparty software tools include DSP libraries, real-time operating systems, and block diagram design tools. Designing an Emulator-Compatible DSP Board (Target) The Analog Devices family of emulators are tools that every DSP developer needs to test and debug hardware and software systems. Analog Devices has supplied an IEEE 1149.1 JTAG test access port (TAP) on each JTAG DSP. Nonintrusive in-circuit emulation is assured by the use of the processor's JTAG interface--the emulator does not affect target system loading or timing. The emulator uses the TAP to access the internal features of the processor, allowing the developer to load code, set breakpoints, observe variables, observe memory, and examine registers. The processor must be halted to send data and commands, but once an operation has been completed by the emulator, the DSP system is set running at full speed with no impact on system timing. To use these emulators, the target board must include a header that connects the DSP's JTAG port to the emulator. For details on target board design issues including mechanical layout, single processor connections, signal buffering, signal termination, and emulator pod logic, see the EE-68: Analog Devices JTAG Emulation Technical Reference on the Analog Devices website (www.analog.com)--use site search on "EE-68." This document is updated regularly to keep pace with improvements to emulator support. Rev. E Evaluation Kit Analog Devices offers a range of EZ-KIT Lite(R) evaluation platforms to use as a cost-effective method to learn more about developing or prototyping applications with Analog Devices processors, platforms, and software tools. Each EZ-KIT Lite includes an evaluation board along with an evaluation suite of the VisualDSP++ development and debugging environment with the C/C++ compiler, assembler, and linker. Also included are sample application programs, power supply, and a USB cable. All evaluation versions of the software tools are limited for use only with the EZ-KIT Lite product. The USB controller on the EZ-KIT Lite board connects the board to the USB port of the user's PC, enabling the VisualDSP++ evaluation suite to emulate the on-board processor in-circuit. This permits the customer to download, execute, and debug programs for the EZ-KIT Lite system. It also allows in-circuit programming of the on-board flash device to store user-specific boot code, enabling the board to run as a standalone unit without being connected to the PC. With a full version of VisualDSP++ installed (sold separately), engineers can develop software for the EZ-KIT Lite or any custom-defined system. Connecting one of Analog Devices JTAG emulators to the EZ-KIT Lite board enables high speed, nonintrusive emulation.

For detailed information on the ADSP-2136x family core architecture and instruction set, refer to the ADSP-21368 SHARC Processor Hardware Reference and the SHARC Processor Programming Reference. | Page 12 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 PIN FUNCTION DESCRIPTIONS The following symbols appear in the Type column of Table 8: A = asynchronous, G = ground, I = input, O = output, O/T = output three-state, P = power supply, S = synchronous, (A/D) = active drive, (O/D) = open-drain, (pd) = pull-down resistor, (pu) = pull-up resistor. The ADSP-21367/ADSP-21368/ADSP-21369 SHARC processors use extensive pin multiplexing to achieve a lower pin count. For complete information on the multiplexing scheme, see the ADSP-21368 SHARC Processor Hardware Reference, "System Design" chapter. Table 8. Pin Descriptions State During/ After Reset (ID = 00x) Description Name Type ADDR23-0 O/T (pu)1 Pulled high/ driven low External Address. The processors output addresses for external memory and peripherals on these pins. DATA31-0 I/O (pu)1 Pulled high/ pulled high External Data. Data pins can be multiplexed to support external memory interface data (I/O), the PDAP (I), FLAGS (I/O), and PWM (O). After reset, all DATA pins are in EMIF mode and FLAG(0-3) pins are in FLAGS mode (default). When configured using the IDP_PDAP_CTL register, IDP Channel 0 scans the external port data pins for parallel input data. ACK I (pu)1 MS0-1 O/T (pu)1 Pulled high/ driven high Memory Select Lines 0-1. These lines are asserted (low) as chip selects for the corresponding banks of external memory. The MS3-0 lines are decoded memory address lines that change at the same time as the other address lines. When no external memory access is occurring, the MS3-0 lines are inactive; they are active, however, when a conditional memory access instruction is executed, whether or not the condition is true. The MS1 pin can be used in EPORT/FLASH boot mode. See the processor hardware reference for more information. RD O/T (pu)1 Pulled high/ driven high External Port Read Enable. RD is asserted whenever the processors read a word from external memory. WR O/T (pu)1 Pulled high/ driven high External Port Write Enable. WR is asserted when the processors write a word to external memory. FLAG[0]/IRQ0 I/O FLAG[0] INPUT FLAG0/Interrupt Request 0. FLAG[1]/IRQ1 I/O FLAG[1] INPUT FLAG1/Interrupt Request 1.

External devices can deassert ACK (low) to add wait states to an external memory access. ACK is used by I/O devices, memory controllers, or other peripherals to hold off completion of an external memory access. Rev. E | Page 13 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 Table 8. Pin Descriptions (Continued) State During/ After Reset (ID = 00x) Description Name Type SDRAS O/T (pu)1 Pulled high/ driven high SDRAM Row Address Strobe. Connect to SDRAM's RAS pin. In conjunction with other SDRAM command pins, defines the operation for the SDRAM to perform. SDCAS O/T (pu)1 Pulled high/ driven high SDRAM Column Address Select. Connect to SDRAM's CAS pin. In conjunction with other SDRAM command pins, defines the operation for the SDRAM to perform. SDWE O/T (pu)1 Pulled high/ driven high SDRAM Write Enable. Connect to SDRAM's WE or W buffer pin. SDCKE O/T (pu)1 Pulled high/ driven high SDRAM Clock Enable. Connect to SDRAM's CKE pin. Enables and disables the CLK signal. For details, see the data sheet supplied with the SDRAM device. SDA10 O/T (pu)1 Pulled high/ driven low SDRAM A10 Pin. Enables applications to refresh an SDRAM in parallel with nonSDRAM accesses. This pin replaces the DSP's A10 pin only during SDRAM accesses. SDCLK0 O/T High-Z/driving SDRAM Clock Output 0. Clock driver for this pin differs from all other clock drivers. See Figure 39 on Page 48. SDCLK1 O/T DAI _P20-1 I/O with programmable pu2 Pulled high/ pulled high Digital Applications Interface. These pins provide the physical interface to the DAI SRU. The DAI SRU configuration registers define the combination of on-chip audiocentric peripheral inputs or outputs connected to the pin, and to the pin's output enable. The configuration registers then determines the exact behavior of the pin. Any input or output signal present in the DAI SRU may be routed to any of these pins. The DAI SRU provides the connection from the serial ports (8), the SRC module, the S/PDIF module, input data ports (2), and the precision clock generators (4), to the DAI_P20-1 pins. Pullups can be disabled via the DAI_PIN_PULLUP register. DPI _P14-1 I/O with programmable pu2 Pulled high/ pulled high Digital Peripheral Interface. These pins provide the physical interface to the DPI SRU. The DPI SRU configuration registers define the combination of on-chip peripheral inputs or outputs connected to the pin and to the pin's output enable. The configuration registers of these peripherals then determines the exact behavior of the pin. Any input or output signal present in the DPI SRU may be routed to any of these pins. The DPI SRU provides the connection from the timers (3), SPIs (2), UARTs (2), flags (12) TWI (1), and general-purpose I/O (9) to the DPI_P14-1 pins. The TWI output is an open-drain output-- so the pins used for I2C data and clock should be connected to logic level 0. Pull-ups can be disabled via the DPI_PIN_PULLUP register. TDI I (pu) Test Data Input (JTAG). Provides serial data for the boundary scan logic. TDO O/T Test Data Output (JTAG). Serial scan output of the boundary scan path. TMS I (pu) Test Mode Select (JTAG). Used to control the test state machine. TCK I Test Clock (JTAG). Provides a clock for JTAG boundary scan. TCK must be asserted (pulsed low) after power-up, or held low for proper operation of the processor TRST I (pu) Test Reset (JTAG). Resets the test state machine. TRST must be asserted (pulsed low) after power-up or held low for proper operation of the processor. SDRAM Clock Output 1. Additional clock for SDRAM devices. For systems with multiple SDRAM devices, handles the increased clock load requirements, eliminating need of offchip clock buffers. Either SDCLK1 or both SDCLKx pins can be three-stated. Clock driver for this pin differs from all other clock drivers. See Figure 39 on Page 48. The SDCLK1 signal is only available on the SBGA package. SDCLK1 is not available on the LQFP_EP package. Rev.

These pins set the start-up clock frequency. See the processor hardware reference for a description of the clock configuration modes. Note that the operating frequency can be changed by programming the PLL multiplier and divider in the PMCTL register at any time after the core comes out of reset. CLKIN I Local Clock In. Used with XTAL. CLKIN is the processor's clock input. It configures the processors to use either its internal clock generator or an external clock source. Connecting the necessary components to CLKIN and XTAL enables the internal clock generator. Connecting the external clock to CLKIN while leaving XTAL unconnected configures the processor to use an external clock such as an external clock oscillator. CLKIN may not be halted, changed, or operated below the specified frequency. XTAL O Crystal Oscillator Terminal. Used in conjunction with CLKIN to drive an external crystal. RESET I Processor Reset. Resets the processor to a known state. Upon deassertion, there is a 4096 CLKIN cycle latency for the PLL to lock. After this time, the core begins program execution from the hardware reset vector address. The RESET input must be asserted (low) at powerup. RESETOUT O BOOT_CFG1-0 I BR4-1 I/O (pu)1 ID2-0 I (pd) Processor ID. Determines which bus request (BR4-1) is used by the ADSP-21368 processor. ID = 001 corresponds to BR1, ID = 010 corresponds to BR2, and so on. Use ID = 000 or 001 in single-processor systems. These lines are a system configuration selection that should be hardwired or only changed at reset. ID = 101,110, and 111 are reserved. RPBA I (pu)1 Rotating Priority Bus Arbitration Select. When RPBA is high, rotating priority for the ADSP-21368 external bus arbitration is selected. When RPBA is low, fixed priority is selected. This signal is a system configuration selection which must be set to the same value on every processor in the system. Driven low/ driven high Description Reset Out. Drives out the core reset signal to an external device. Boot Configuration Select. These pins select the boot mode for the processor. The BOOT_CFG pins must be valid before reset is asserted. See the processor hardware reference for a description of the boot modes. Pulled high/ pulled high External Bus Request. Used by the ADSP-21368 processor to arbitrate for bus mastership. A processor only drives its own BRx line (corresponding to the value of its ID2-0 inputs) and monitors all others. In a system with less than four processors, the unused BRx pins should be tied high; the processor's own BRx line must not be tied high or low because it is an output. The pull-up is always enabled on the ADSP-21367 and ADSP-21369 processors. The pull-up on the ADSP-21368 processor is only enabled on the processor with ID2-0 = 00x Pull-up can be enabled/disabled, value of pull-up cannot be programmed. Rev.

Circuitry external to the processor must be designed for compatibility with these signal characteristics. Switching characteristics describe what the processor will do in a given circumstance. Use switching characteristics to ensure that any timing requirement of a device connected to the processor (such as memory) is satisfied. Timing Requirements apply to signals that are controlled by circuitry external to the processor, such as the data input for a read operation. Timing requirements guarantee that the processor operates correctly with other devices. ESD CAUTION ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality. MAXIMUM POWER DISSIPATION See Estimating Power Dissipation for ADSP-21368 SHARC Processors (EE-299) for detailed thermal and power information regarding maximum power dissipation. For information on package thermal specifications, see Thermal Characteristics on Page 50. ABSOLUTE MAXIMUM RATINGS Stresses greater than those listed in Table 10 may cause permanent damage to the device. These are stress ratings only; functional operation of the device at these or any other conditions greater than those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Rev. E Core Clock Requirements The processor's internal clock (a multiple of CLKIN) provides the clock signal for timing internal memory, processor core, and serial ports. During reset, program the ratio between the processor's internal clock frequency and external (CLKIN) clock frequency with the CLK_CFG1-0 pins. The processor's internal clock switches at higher frequencies than the system input clock (CLKIN). To generate the internal clock, the processor uses an internal phase-locked loop (PLL, see Figure 5). This PLL-based clocking minimizes the skew between the system clock (CLKIN) signal and the processor's internal clock. Voltage Controlled Oscillator In application designs, the PLL multiplier value should be selected in such a way that the VCO frequency never exceeds fVCO specified in Table 13. * The product of CLKIN and PLLM must never exceed 1/2 of fVCO (max) in Table 13 if the input divider is not enabled (INDIV = 0). | Page 18 of 60 | July 2009 ADSP-21367/ADSP-21368/ADSP-21369 * The product of CLKIN and PLLM must never exceed fVCO (max) in Table 13 if the input divider is enabled (INDIV = 1). Note the definitions of the clock periods that are a function of CLKIN and the appropriate ratio control shown in and Table 11. All of the timing specifications for the ADSP-2136x peripherals are defined in relation to tPCLK. See the peripheral specific timing section for each peripheral's timing information. The VCO frequency is calculated as follows: fVCO = 2 x PLLM x fINPUT fCCLK = (2 x PLLM x fINPUT) / (2 x PLLD) Table 11. Clock Periods where: Timing Requirements tCK tCCLK tPCLK fVCO = VCO output PLLM = Multiplier value programmed in the PMCTL register. During reset, the PLLM value is derived from the ratio selected using the CLK_CFG pins in hardware. PLLD = Divider value 1, 2, 4, or 8 based on the PLLD value programmed on the PMCTL register. During reset this value is 1.

This leakage current results from the weak internal pull-up resistor on this pin being enabled during power-up. The timing requirements for processor start-up are given in Table 12.

Refer to your crystal oscillator manufacturer's data sheet for start-up time. Assume a 25 ms maximum oscillator start-up time if using the XTAL pin and internal oscillator circuit in conjunction with an external crystal. 3 Applies after the power-up sequence is complete. Subsequent resets require RESET to be held low a minimum of four CLKIN cycles in order to properly initialize and propagate default states at all I/O pins. 4 The 4096 cycle count depends on tsrst specification in Table 14. If setup time is not met, 1 additional CLKIN cycle may be added to the core reset time, resulting in 4097 cycles maximum.
