description
●The TMS320C67x DSPs (including the TMS320C6711, TMS320C6711B, TMS320C6711C, TMS320C6711D devices†) compose the floating-point DSP family in the TMS320C6000 DSP platform. The C6711, C6711B, C6711C, and C6711D devices are based on the high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSPs an excellent choice for multichannel and multifunction applications.
