DescriptionVideo/imaging Fixed-point Digital Signal Processor<<<>>>the TMS320C64x TMS320DM640 Devices) Are The Highest-performance Fixed-point DSP Generation in The TMS320C6000 DSP Platform. The TMS320DM641 And TMS320DM640 (DM641 And 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 32-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 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.

This data sheet revision history highlights the technical changes made to the SPRS222A device-specific data sheet to make an SPRS222B revision. Scope: Applicable updates to the C64x device family, specifically relating to the TMS320DM641/TMS320DM640 devices, have been incorporated. Changed DM641/DM640 device-specific information to the advance information (AI) stage of development. Highlights:

D Updated/changed timings for Electrical Characteristics, Input and Output Clocks Timing, AECLKIN;

Asynchronous Memory; Programmable Synchronous Interface; Synchronous DRAM; Multichannel Buffered Serial Port; and Video Port Timings D Corrected timing parameter signal descriptions to match terminal functions

ADDS/CHANGES/DELETES Global change: Changed all EMIF signal names to be specific to EMIFA Updated the EMAC/MDIO peripherals detailed descriptions, the EMAC Control Registers table, the EMAC Statistics Registers table, and the MDIO Registers table to support an EMAC module that has 8 Independent Transmit (TX) Channels and 1 Receive (RX) Channel and does not support receive quality of service (QOS).

Table 1-1, Characteristics of the DM641 Processor: Changed Product Status from "PP" to "AI" (Advance Information) Table 1-2, Characteristics of the DM640 Processor: Changed Product Status from "PP" to "AI" (Advance Information) Table 1-6, L2 Cache Registers (C64x): Split the "Reserved" row between hex address range 1FFC" Added the L2 EDMA Access Control Register (EDMAWEIGHT) to the hex address location 0184 1000 Device Configurations section, Peripheral Selection at Device Reset: Added "For proper DM641/DM640 device operation, the GP0[0] pin [M5] (IPD) must remain low at device reset." bullet JTAG ID Register Description section: Changed the JTAG ID register address location from "0x01B3 F008" Figure 2-9, Configuration Example A for (1 8-Bit Video Port McASP0 + VIC I2C0 + EMIF) [TBD Application]: Removed the shading from the "McBSP1" block; module is active Table 2-9, Terminal Functions: Updated/changed the following DM641/DM640 RSV SIGNAL NAMEs to include their TYPE, and IPD/IPU column information: E14 I IPD; I AC4 O/Z AD3 O/Z and AF3 O IPU Documentation Support section: Added the "TMS320DM64x Power Consumption Summary application report (literature number SPRA962)" reference Figure 2-12, External PLL Circuitry for Either PLL Multiply Modes or x1 (Bypass) Mode: Deleted "L2 Clock" from the /2 outputs
