说明
The TMS320C64x+™ DSPs (including the TMS320DM647, TMS320DM648 devices) are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The DM647, DM648 devices are based on the third-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSPs an excellent choice for digital media applications. The C64x+™ devices are upward code-compatible from previous devices that are part of the C6000™ DSP platform. The C64x™ DSPs support added functionality and have an expanded instruction set from previous devices.
Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP and C64x+ CPU, respectively.
