Description

The TMS320C64x+ DSPs (including the TMS320C6474 device) are the highest-performance multicore DSP generation in the TMS320C6000™ DSP platform.

The C6474 device is based on the third-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI).

The C64x+™ devices are upward code-compatible from previous devices that are part of the C6000™ DSP platform.
