Overview
The TMS320C6416T, produced by Texas Instruments, is part of the highest-performance fixed-point DSP generation within the TMS320C6000 DSP platform. This device is based on the second-generation high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture (VelociTI.2), making it an excellent choice for wireless infrastructure applications. The C6416T is fully software-compatible with the C62x™ devices and is pin-compatible with the C6414T and C6415T devices. It features two high-performance embedded coprocessors: the Viterbi Decoder Coprocessor (VCP) and the Turbo Decoder Coprocessor (TCP), which significantly enhance channel-decoding operations.
