TMS320C64 C64x Fixed Point DSP

Texas Instruments TMS320C64x+™ DSPs (including the TMS320C6455 device) are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The C64x+™ devices are upward code-compatible from previous devices that are part of the C6000™ DSP platform. The C64x+ DSP core employs eight functional units, two register files, and two data paths. Like the earlier C6000 devices, two of these eight functional units are multipliers or .M units. Each C64x+ .M unit doubles the multiply throughput versus the C64x core by performing four 16-bit x 16-bit multiply-accumulates (MACs) every clock cycle. Thus, eight 16-bit x 16-bit MACs can be executed every cycle on the C64x+ core. At a 1.2 GHz clock rate, this means 9,600 16-bit MMACs can occur every second. Moreover, each multiplier on the C64x+ core can compute one 32-bit x 32-bit MAC or four 8-bit x 8-bit MACs every clock cycle.

The TMS320C64x+ DSPs come in a variety of speed and peripheral configurations for applications including audio, radar and more.
