June 2003 − Revised October 2005SPRS222E

1.2 Description

The TMS320C64x™ DSPs (including the TMS320DM641 and TMS320DM640 devices) are the
highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The TMS320DM641
(DM641) and TMS320DM640 (DM640) devices are based on the second-generation high-performance,
advanced VelociTI™ very-long-instruction-word (VLIW) architecture (VelociTI.2™) developed by Texas
Instruments (TI), making these DSPs an excellent choice for digital media 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 DM641
device offers cost-effective solutions to high-performance DSP programming challenges.

With performance of up to 3200 million instructions per second (MIPS) at a clock rate of 400 MHz, the DM640
device offers cost-effective solutions to high-performance DSP programming challenges.

The DM641/DM640 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 video and imaging applications and extend the
parallelism of the VelociTI™ architecture. The DM641 can produce four 16-bit multiply-accumulates (MACs)
per cycle for a total of 2400 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of
4800 MMACS. The DM640 can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of
1600 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 3200 MMACS. The
DM641/DM640 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip
peripherals similar to the other C6000™ DSP platform devices.

The DM641/DM640 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 a 1-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: two configurable video ports (DM641); one
configurable video port (DM640); a 10/100 Mb/s Ethernet MAC (EMAC); a management data input/output
(MDIO) module; a VCXO interpolated control port (VIC); one 4-bit multichannel buffered audio serial port
(McASP0); an inter-integrated circuit (I2C) Bus module; two multichannel buffered serial ports (McBSPs);
three 32-bit general-purpose timers; a 16-bit host-port interface (HPI16) [DM641]; an 8-pin general-purpose
input/output port (GP0) with programmable interrupt/event generation modes; and a 32-bit glueless external
memory interface (EMIFA), which is capable of interfacing to synchronous and asynchronous memories and
peripherals.

The DM641 device has two single-channel 8-bit configurable video port peripherals (VP0 and VP1). The
DM640 device has one single-channel 8-bit configurable video port peripheral (VP0). These video port
peripherals provide a glueless interface to common video decoder and encoder devices. The DM641/DM640
video port peripherals support multiple resolutions and video standards (e. g., CCIR601 and ITU−BT.656).

These video port peripherals are configurable and can support either video capture and/or video display
modes.

For more details on the Video Port peripherals, see the TMS320C64x DSP Video Port/VCXO Interpolated
Control (VIC) Port Reference Guide (literature number SPRU629).

The McASP0 port supports one transmit and one receive clock zone, with four serial data pins which can be
individually allocated to any of the two zones. The serial port supports time-division multiplexing on each pin
from 2 to 32 time slots. The DM641/DM640 has sufficient bandwidth to support all 4 serial data pins
transmitting a 192-kHz stereo signal. Serial data in each zone may be transmitted and received on multiple
serial data pins simultaneously and formatted in a multitude of variations on the Philips Inter-IC Sound (I

June 2003 − Revised October 2005 SPRS222E

In addition, the McASP0 transmitter may be programmed to output multiple S/PDIF, IEC60958, AES-3,
CP-430 encoded data channels simultaneously, with a single RAM containing the full implementation of user
data and channel status fields.

McASP0 also provides extensive error-checking and recovery features, such as the bad clock detection circuit
for each high-frequency master clock which verifies that the master clock is within a programmed frequency
range.

The VCXO interpolated control (VIC) port provides digital-to-analog conversion with resolution from 9-bits to
up to 16-bits. The output of the VIC is a single bit interpolated D/A output. For more details on the VIC port,
see the TMS320C64x DSP Video Port/VCXO Interpolated Control (VIC) Port Reference Guide (literature
number SPRU629).

The ethernet media access controller (EMAC) provides an efficient interface between the DM641/DM640 DSP
core processor and the network. The DM641/DM640 EMAC support both 10Base-T and 100Base-TX, or 10
Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex, with hardware flow control and quality of
service (QOS) support. The DM641/DM640 EMAC makes use of a custom interface to the DSP core that
allows efficient data transmission and reception. For more details on the EMAC, see the TMS320C6000 DSP

Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO) Module Reference
Guide (literature number SPRU628).

The management data input/output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system. Once a PHY candidate has been selected by the DSP, the MDIO
module transparently monitors its link state by reading the PHY status register. Link change events are stored
in the MDIO module and can optionally interrupt the DSP, allowing the DSP to poll the link status of the device
without continuously performing costly MDIO accesses. For more details on the MDIO, see the

TMS320C6000 DSP Ethernet Media Access Controller (EMAC) / Management Data Input/Output (MDIO)
Module Reference Guide (literature number SPRU628).

The I2C0 port on the TMS320DM641/DM640 allows the DSP to easily control peripheral devices and
communicate with a host processor. In addition, the standard multichannel buffered serial port (McBSP) may
be used to communicate with serial peripheral interface (SPI) mode peripheral devices.

The DM641/DM640 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

1.6 CPU (DSP Core) Description

The CPU fetches VelociTI™ 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:

• 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 1−2]. 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. This is a key
factor for video and imaging applications.

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

23

June 2003 − Revised October 2005 SPRS222E

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.

For more details on the C64x CPU functional units enhancements, see the following documents:
