The TMS320C64x? DSPs (including the TMS320DM642 device) are the highest-performance fixed-point DSP generation in the TMS320C6000? DSP platform. The TMS320DM642 (DM642) device is 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 5760 million instructions per second (MIPS) at a clock rate of 720 MHz, the DM642 device offers cost-effective solutions to high-performance DSP programming challenges. The DM642 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 DM642 can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 2880 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 5760 MMACS. The DM642 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000? DSP platform devices.
