TMS320DM642AZDK5

Product Summary

The TMS320C64x ? DSPs (including the TMS320DM642 device) are the highest-performance fixed-
DSP generation in the TMS320C6000 ? DSP platform. The TMS320DM642 (DM642) device is base
the second-generation high-performance, advanced VelociTI ? very-long-instruction-word (VLIW) arch
ture (VelociTI.2 ? ) developed by Texas Instruments (TI), making these DSPs an excellent choic

<FONT face=Verdana>With performance of up to 5760 million instructions per second (MIPS) at a clock rate of 720 MHz, the<BR>DM642 device offers cost-effective solutions to high-performance DSP programming challenges. The<BR>DM642 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of<BR>array processors. The C64x ? DSP core processor has 64 general-purpose registers of 32-bit word length<BR>and eight highly independent functional units two multipliers for a 32-bit result and six arithmetic logic<BR>units (ALUs) with VelociTI.2 ? extensions. The VelociTI.2 ? extensions in the eight functional units<BR>include new instructions to accelerate the performance in video and imaging applications and extend the<BR>parallelism of the VelociTI ? architecture. The DM642 can produce four 16-bit multiply-accumulates<BR>(MACs) per cycle for a total of 2880 million MACs per second (MMACS), or eight 8-bit MACs per cycle for<BR>a total of 5760 MMACS. The DM642 DSP also has application-specific hardware logic, on-chip memory,<BR>and additional on-chip peripherals similar to the other C6000 ? DSP platform devices.</FONT>
