The TMS320C6416 (C6416) device is based on the second-generation high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture (VelocTI.2) developed by Texas Instruments (TI), making these DSPs an excellent choice for multichannel and multifunction applications. The C64x is a code-compatible member of the C6000 DSP platform. The C6416 has two high-performance embedded coprocessors [Viterbi Decoder Coprocessor (VCP) and Turbo Decoder Coprocessor (TCP)] that significantly speed up channel-decoding operations on-chip. The VCP operating at CPU clock divided-by-4 can decode over 500 7.95-Kbps adaptive multi-rate (AMR) [K = 9, R = 1/3] voice channels. The VCP supports constraint lengths K = 5, 6, 7, 8, and 9, rates R = 1/2, 1/3, and 1/4, and flexible polynomials, while generating hard decisions or soft decisions. The TCP operating at CPU clock divided-by-2 can decode up to thirty-six 384-Kbps or six 2-Mbps turbo encoded channels (assuming 6 iterations). The TCP implements the max*log-map algorithm and is designed to support all polynomials and rates required by Third-Generation Partnership Projects (3GPP and 3GPP2), with fully programmable frame length and turbo interleaver. Decoding parameters such as the number of iterations and stopping criteria are also programmable. Communications between the VCP/TCP and the CPU are carried out through the EDMA controller. The C6416 uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The Level 1 program cache (L1P) is a 128-Kbit direct mapped cache and the Level 1 data cache (L1D) is a 128-Kbit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 8-Mbit memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two. The peripheral set includes three multichannel buffered serial ports (McBSPs); an 8-bit Universal Test and Operations PHY Interface for Asynchronous Transfer Mode (ATM) Slave [UTOPIA Slave] port; three 32-bit general-purpose timers; a user-configurable 16-bit or 32-bit host-port interface (HPI16/HPI32); a 32-bit peripheral component interconnect (PCI); a general-purpose input/output port (GPIO) with 16 GPIO pins; and two glueless external memory interfaces (64-bit EMIFA and 16-bit EMIFB), both of which are capable of interfacing to synchronous and asynchronous memories and peripherals. The C6416 has a complete set of development tools which includes: a new C compiler, an assembly optimizer to simplify programming and scheduling, and a Windows debugger interface for visibility into source code execution.

POST OFFICE BOX 1443 * HOUSTON, TEXAS 77251-1443 3 PRODUCT PREVIEW With performance of up to 4800 million instructions per second (MIPS) at a clock rate of 600 MHz, the C6416 device offers cost-effective solutions to high-performance DSP programming challenges. The C6416 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. The C64x DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly independent functional units--two multipliers for a 32-bit result and six arithmetic logic units (ALUs)-- with VelociTI.2 extensions. The VelociTI.2 extensions in the eight functional units include new instructions to accelerate the performance in key applications and extend the parallelism of the VelociTI architecture. The C6416 can produce two 32-bit multiply-accumulates (MACs) per cycle for a total of 1200 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4800 MMACS. The C6416 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices.

The VelociTI VLIW architecture features controls by which all eight units do not have to be supplied with instructions if they are not ready to execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute packet as the previous instruction, or whether it should be executed in the following clock as a part of the next execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The variable-length execute packets are a key memory-saving feature, distinguishing the C64x CPUs from other VLIW architectures. The C64x VelociTI.2 extensions add enhancements to the TMS320C62x DSP VelociTI architecture. These enhancements include: Register file enhancements Data path extensions Quad 8-bit and dual 16-bit extensions with data flow enhancements Additional functional unit hardware Increased orthogonality of the instruction set Additional instructions that reduce code size and increase register flexibility The CPU features two sets of functional units. Each set contains four units and a register file. One set contains functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register files each contain 32 32-bit registers for a total of 64 general-purpose registers. In addition to supporting the packed 16-bit and 32-/40-bit fixed-point data types found in the C62x VelociTI VLIW architecture, the C64x register files also support packed 8-bit data and 64-bit fixed-point data types. The two sets of functional units, along with two register files, compose sides A and B of the CPU [see the functional block and CPU (DSP core) diagram, and Figure 1]. The four functional units on each side of the CPU can freely share the 32 registers belonging to that side. Additionally, each side features a "data cross path"--a single data bus connected to all the registers on the other side, by which the two sets of functional units can access data from the register files on the opposite side. The C64x CPU pipelines data-cross-path accesses over multiple clock cycles. This allows the same register to be used as a data-cross-path operand by multiple functional units in the same execute packet. All functional units in the C64x CPU can access operands via the data cross path. Register access by functional units on the same side of the CPU as the register file can service all the units in a single clock cycle. On the C64x CPU, a delay clock is introduced whenever an instruction attempts to read a register via a data cross path if that register was updated in the previous clock cycle. In addition to the C62x DSP fixed-point instructions, the C64x DSP includes a comprehensive collection of quad 8-bit and dual 16-bit instruction set extensions. These VelociTI.2 extensions allow the C64x CPU to operate directly on packed data to streamline data flow and increase instruction set efficiency. Another key feature of the C64x CPU is the load/store architecture, where all instructions operate on registers (as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data transfers between the register files and the memory. The data address driven by the .D units allows data addresses generated from one register file to be used to load or store data to or from the other register file. The C64x .D units can load and store bytes (8 bits), half-words (16 bits), and words (32 bits) with a single instruction. And with the new data path extensions, the C64x .D unit can load and store doublewords (64 bits) with a single instruction. Furthermore, the non-aligned load and store instructions allow the .D units to access words and doublewords on any byte boundary. The C64x CPU supports a variety of indirect addressing modes using either linear- or circular-addressing with 5- or 15-bit offsets. All instructions are conditional, and most can access any one of the 64 registers. Some registers, however, are singled out to support specific addressing modes or to hold the condition for conditional instructions (if the condition is not automatically "true").

POST OFFICE BOX 1443 * HOUSTON, TEXAS 77251-1443 7 PRODUCT PREVIEW D D D D D D TMS320C6416 FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS164C - FEBRUARY 2001 - REVISED SEPTEMBER 2001 CPU (DSP core) description (continued) The two .M functional units perform all multiplication operations. Each of the C64x .M units can perform two 16 x 16-bit multiplies or four 8 x 8-bit multiplies per clock cycle. The .M unit can also perform 16 x 32-bit multiply operations, dual 16 x 16-bit multiplies with add/subtract operations, and quad 8 x 8-bit multiplies with add operations. In addition to standard multiplies, the C64x .M units include bit-count, rotate, Galois field multiplies, and bidirectional variable shift hardware. The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results available every clock cycle. The arithmetic and logical functions on the C64x CPU include single 32-bit, dual 16-bit, and quad 8-bit operations. PRODUCT PREVIEW The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory. The 32-bit instructions destined for the individual functional units are "linked" together by "1" bits in the least significant bit (LSB) position of the instructions. The instructions that are "chained" together for simultaneous execution (up to eight in total) compose an execute packet. A "0" in the LSB of an instruction breaks the chain, effectively placing the instructions that follow it in the next execute packet. A C64x DSP device enhancement now allows execute packets to cross fetch-packet boundaries. In the TMS320C62x/TMS320C67x DSP devices, if an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in the next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. In the C64x DSP device, the execute boundary restrictions have been removed, thereby, eliminating all of the NOPs added to pad the fetch packet, and thus, decreasing the overall code size. The number of execute packets within a fetch packet can vary from one to eight. Execute packets are dispatched to their respective functional units at the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from the current fetch packet have been dispatched. After decoding, the instructions simultaneously drive all active functional units for a maximum execution rate of eight instructions every clock cycle. While most results are stored in 32-bit registers, they can be subsequently moved to memory as bytes, half-words, or doublewords. All load and store instructions are byte-, half-word-, word-, or doubleword-addressable.

Also, the multiplexed GPIO/PCI pins can be used as GPIO with the proper software configuration of the GPIO enable and direction registers (for more details, see Table 7). - If the PCI is enabled (PCI_EN = 1), the HPI peripheral is disabled. This means all multiplexed HPI/PCI pins function as PCI. Also, the multiplexed GPIO/PCI pins function as PCI pins (for more details, see Table 7). - The MCBSP2_EN pin, in combination with the PCI_EN pin, controls the selection of the McBSP2 peripheral and the PCI internal EEPROM (for more details, see Table 5 and its footnotes). other device configurations Table 6 describes the C6416 device configuration pins, which are set up via external pullup/pulldown resistors through the specified EMIFB address bus pins (BEA[20:13, 9, 8]) and the HD5 pin.

The MCBSP2_EN pin must be driven valid at all times and the user can switch values throughout device operation. The only time McBSP2 is disabled is when both PCI_EN = 1 and MCBSP2_EN = 0. This configuration enables, at reset, the auto-initialization of the PCI peripheral through the PCI internal EEPROM [provided the PCI EEPROM Auto-Initialization pin (BEA13) is pulled up (EEAI = 1)]. The user can then enable the McBSP2 peripheral (disabling EEPROM) by dynamically changing MCBSP2_EN to a "1" after the device is initialized (out of reset). 1 TMS320C6416 FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS164C - FEBRUARY 2001 - REVISED SEPTEMBER 2001 DEVICE CONFIGURATIONS (CONTINUED) Table 6.

Some of these pins are configured by software, and the others are configured by external pullup/pulldown resistors only at reset. Those muxed pins that are configured by software can be programmed to switch functionalities at any time. Those muxed pins that are configured by external pullup/pulldown resistors are mutually exclusive; only one peripheral has primary control of the function of these pins after reset. Table 7 identifies the multiplexed pins on the C6416 device; shows the default (primary) function and the default settings after reset; and describes the pins, registers, etc. necessary to configure specific multiplexed functions. debugging considerations Internal pullup/pulldown resistors also exist on the non-configuration pins on the BEA bus (BEA[12, 10, 7:1]). Do not oppose the internal pullup/pulldown resistors on these non-configuration pins with external pullup/pulldown resistors. If an external controller provides signals to these non-configuration pins, these signals must be driven to the default state of the pins at reset, or not be driven at all. For the internal pullup/pulldown resistors for all device pins, see the terminal functions table.

Each TMS320 DSP family member has one of three prefixes: TMX, TMP, or TMS. Texas Instruments recommends two of three possible prefix designators for support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX / TMDX) through fully qualified production devices/tools (TMS / TMDS). Device development evolutionary flow: TMX Experimental device that is not necessarily representative of the final device's electrical specifications TMP Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification TMS Fully qualified production device TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing. TMDS Fully qualified development-support product TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices ( TMX or TMP) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used. To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all TMS320 DSP devices and support tools. Each TMS320 DSP family member has one of three prefixes: TMX, TMP, or TMS. Texas Instruments recommends two of three possible prefix designators for support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX / TMDX) through fully qualified production devices/tools (TMS / TMDS). TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, GLZ), the temperature range (for example, blank is the default commercial temperature range), and the device speed range in megahertz (for example, -600 is 600 MHz).

TMS320C6416 FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS164C - FEBRUARY 2001 - REVISED SEPTEMBER 2001 clock PLL Most of the internal C64x DSP clocks are generated from a single source through the CLKIN pin. This source clock either drives the PLL, which multiplies the source clock frequency to generate the internal CPU clock, or bypasses the PLL to become the internal CPU clock. To use the PLL to generate the CPU clock, the external PLL filter circuit must be properly designed. Figure 5 shows the external PLL circuitry for either x1 (PLL bypass) or other PLL multiply modes. To minimize the clock jitter, a single clean power supply should power both the C64x DSP device and the external clock oscillator circuit. The minimum CLKIN rise and fall times should also be observed. For the input clock timing requirements, see the input and output clocks electricals section. Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clock source must meet the DSP requirements in this data sheet (see the electrical characteristics over recommended ranges of suppy voltage and operating case temperature table and the input and output clocks electricals section).

However, systems should be designed to ensure that neither supply is powered up for extended periods of time if the other supply is below the proper operating voltage. system-level design considerations System-level design considerations, such as bus contention, may require supply sequencing to be implemented. In this case, the core supply should be powered up at the same time as, or prior to (and powered down after), the I/O buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the output buffers are powered up, thus, preventing bus contention with other chips on the board. power-supply design considerations A dual-power supply with simultaneous sequencing can be used to eliminate the delay between core and I/O power up. A Schottky diode can also be used to tie the core rail to the I/O rail. PRODUCT PREVIEW Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize inductance and resistance in the power delivery path. Additionally, when designing for high-performance applications utilizing the C6000 platform of DSPs, the PC board should include separate power planes for core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors. 46 POST OFFICE BOX 1443 * HOUSTON, TEXAS 77251-1443 TMS320C6416 FIXED-POINT DIGITAL SIGNAL PROCESSOR SPRS164C - FEBRUARY 2001 - REVISED SEPTEMBER 2001 absolute maximum ratings over operating case temperature range (unless otherwise noted) Supply voltage ranges: CVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . - 0.3 V to 2.3 V DVDD (see Note 1) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 V to 4 V Input voltage ranges: (except PCI), VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 V to 4 V (PCI), VIP . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.5 V to DVDD + 0.5 V Output voltage ranges: (except PCI), VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.3 V to 4 V (PCI), VOP . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -0.5 V to DVDD + 0.5 V Operating case temperature range, TC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0_C to 90_C Storage temperature range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -65_C to 150_C Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device.

TI highly recommends that users design-in a supply that can handle multiple voltages within this range (i.e., 1.2 V, 1.25 V, 1.3 V, 1.35 V, 1.4 V with 3% tolerances) by implementing simple board changes such as reference resistor values or input pin configuration modifications. Examples of such supplies include the PT4660, PT5500, PT5520, PT6440, and PT6930 series from Power Trends, a subsidiary of Texas Instruments. Not incorporating a flexible supply may limit the system's ability to easily adapt to future versions of C641x devices.

As a good board design practice, such delays must always be taken into account. Timing values may be adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. If needed, external logic hardware such as buffers may be used to compensate any timing differences. For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin, but also tends to improve the input hold time margins (see Table 10 and Figure 9). Figure 9 represents a general transfer between the DSP and an external device. The figure also represents board route delays and how they are perceived by the DSP and the external device. Table 10.
