POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443
description
The TMS320C64x DSPs (including the TMS320C6416 device) are the highest-performance fixed-point DSP
generation in the TMS320C6000 DSP platform. 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.
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 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.

CPU (DSP core) description
The CPU fetches V elociTI advanced very-long instruction words (VLIWs) (256 bits wide) to supply up to eight
32-bit instructions to the eight functional units during every clock cycle. 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:
DRegister file enhancements
DData path extensions
DQuad 8-bit and dual 16-bit extensions with data flow enhancements
DAdditional functional unit hardware
DIncreased orthogonality of the instruction set
DAdditional 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”).

CPU (DSP core) description (continued)
The two .M functional units perform all multiplication operations. Each of the C64x .M units can perform two
16 × 16-bit multiplies or four 8 ×8-bit multiplies per clock cycle. The .M unit can also perform 16 ×32-bit multiply
operations, dual 16 ×16-bit multiplies with add/subtract operations, and quad 8 ×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.
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.

DEVICE CONFIGURATIONS
The C6416 peripheral selections and other device configurations are determined by external pullup/pulldown
resistors on the following pins (all of which are latched during device reset):
Dperipherals selection
–BEA11 (UTOPIA_EN)
–PCI_EN
–MCBSP2_EN (see Table 5 footnotes)
Dother device configurations
–BEA[20:13, 9, 8]
–HD5
peripherals selection
Some C6416 peripherals share the same pins (internally muxed) and are mutually exclusive (i.e., HPI,
general-purpose input/output pins GP[15:9], PCI and its internal EEPROM, McBSP1, McBSP2, and UTOPIA).
The VCP/TCP coprocessors and other C6416 peripherals (i.e., the Timers, McBSP0, and the GP[8:0] pins), are
always available.
DUTOPIA and McBSP1 peripherals
The UTOPIA_EN pin (BEA11) is latched at reset. This pin selects whether the UTOPIA peripheral or
McBSP1 peripheral is functionally enabled (see Table 4).
Table 4. UTOPIA_EN Peripheral Selection (McBSP1 and UTOPIA)
PERIPHERAL SELECTION PERIPHERALS SELECTED
UTOPIA_EN

and all other standalone UTOPIA pins are tied-of f (Hi-Z).
1√UTOPIA is enabled and McBSP1 is disabled.
This means all multiplexed McBSP1/UTOPIA pins now function as
UTOPIA and all other standalone McBSP1 pins are tied-off (Hi-Z).

†The PCI_EN pin must be driven valid at all times and the user must not switch values throughout device operation.
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).
–If the PCI is disabled (PCI_EN = 0), the HPI peripheral is enabled and GP[15:9] pins can be programmed
as GPIO, provided the GPxEN and GPxDIR bits are properly configured.
This means all multiplexed HPI/PCI pins function as HPI and all standalone PCI pins (PCBE0 and
XSP_CS) are tied-off (Hi-Z). 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 T able 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).

DEVICE CONFIGURATIONS (CONTINUED)
multiplexed pins
Multiplexed pins are pins that are shared by more than one peripheral and are internally multiplexed. 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. T able 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
It is recommended that external connections be provided to device configuration pins, including
CLKMODE[1:0], BEA[20:13, 11, 9, 8], HD5/AD5, PCI_EN, and MCBSP2_EN. Although internal pullup/pulldown
resistors exist on these pins, providing external connectivity adds convenience to the user in debugging and
flexibility in switching operating modes.
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.

device and development-support tool nomenclature
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).
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
Support tool development evolutionary flow:
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. T exas 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,

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). Figure 4 provides a legend for
reading the complete device name for any TMS320C6000 DSP platform member.

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). Table 8 lists some examples of compatible CLKIN external clock sources:

NOTES: A. Place all PLL external components (C1, C2, and the EMI Filter) as close to the C6000 DSP device as possible. For the best
performance, TI recommends that all the PLL external components be on a single side of the board without jumpers, switches, or
components other than the ones shown.
B. For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (C1, C2, and the EMI
Filter).
C. The 3.3-V supply for the EMI filter must be from the same 3.3-V power plane supplying the I/O voltage, DVDD.

‡Use external pullup resistors on the CLKMODE pins (CLKMODE1 and CLKMODE0) to set the C6416 device to one of the valid PLL multiply
clock modes (x6 or x12). With internal pulldown resistors on the CLKMODE pins (CLKMODE1, CLKMODE0), the default clock mode is x1
(bypass).
§Under some operating conditions, the maximum PLL lock time may vary by as much as 150% from the specified typical value. For example, if

power-supply sequencing
TI DSPs do not require specific power sequencing between the core supply and the I/O supply. 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 buf fers 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.
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.

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 T exas Instruments. Not
incorporating a flexible supply may limit the system’s ability to easily adapt to future versions of C641x devices.

PARAMETER MEASUREMENT INFORMATION (CONTINUED)
timing parameters and board routing analysis
The timing parameter values specified in this data sheet do not include delays by board routings. 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.

§The EKxHZ bits in the EMIF Global Control register (GBLCTL) determine the state of the ECLKOUTx signals during HOLDA. If EKxHZ = 0,
ECLKOUTx continues clocking during Hold mode. If EKxHZ = 1, ECLKOUTx goes to high impedance during Hold mode, as shown in Figure 29.
¶All pending EMIF transactions are allowed to complete before HOLDA is asserted. If no bus transactions are occurring, then the minimum delay
time can be achieved. Also, bus hold can be indefinitely delayed by setting NOHOLD = 1.

‡P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
¶HCS enables HRDY, and HRDY is always low when HCS is high. The case where HRDY goes high when HCS falls indicates that HPI is busy
completing a previous HPID write or READ with autoincrement.
#This parameter is used during an HPID read. At the beginning of a word transfer (HPI32) or the first half-word transfer (HPI16) on the falling edge
of HSTROBE, the HPI sends the request to the EDMA internal address generation hardware, and HRDY remains high until the EDMA internal
address generation hardware loads the requested data into HPID.
|| This parameter is used after a word (HPI32) or the second half-word (HPI16) of an HPID write or autoincrement read. HRDY remains low if the
access is not an HPID write or autoincrement read. Reading or writing to HPIC or HPIA does not affect the HRDY signal.

‡P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
§The maximum bit rate for McBSP-to-McBSP communications is 100 MHz; therefore, the minimum CLKR/X clock cycle is either four times the
CPU cycle time (4P), or 10 ns (100 MHz), whichever value is larger. For example, when running parts at 600 MHz (P = 1.67 ns), use 10 ns as
the minimum CLKR/X clock cycle (by setting the appropriate CLKGDV ratio or external clock source). When running parts at 200 MHz (P = 5 ns),
use 4P = 20 ns (50 MHz) as the minimum CLKR/X clock cycle. The maximum bit rate for McBSP-to-McBSP communications applies to the
following hardware configuration: the serial port is a Master of the clock and frame syncs (with CLKR connected to CLKX, FSR connected to
FSX, CLKXM = FSXM = 1, and CLKRM = FSRM = 0) in data delay 1 or 2 mode (R/XDATDLY = 01b or 10b) and the other device the McBSP

§P = 1/CPU clock frequency in ns. For example, when running parts at 600 MHz, use P = 1.67 ns.
¶The maximum bit rate for McBSP-to-McBSP communications is 100 MHz; therefore, the minimum CLKR/X clock cycle is either four times the

#C = H or L

L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
= (CLKGDV + 1)/2 * S if CLKGDV is odd or zero
CLKGDV should be set appropriately to ensure the McBSP bit rate does not exceed the maximum limit (see ¶ footnote above).
|| Extra delay from CLKX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.
if DXENA = 0, then D1 = D2 = 0
if DXENA = 1, then D1 = 2P, D2 = 4P
