Overview
The TMS320C6454BZTZ2 is a high-performance fixed-point digital signal processor (DSP) from Texas Instruments, part of the TMS320C64x+™ DSP family. This device is based on the third-generation advanced VelociTI™ very-long-instruction-word (VLIW) architecture, making it an excellent choice for demanding applications such as video and telecom infrastructure, imaging/medical, and wireless infrastructure. The C6454 offers a lower cost, pin-compatible migration path for users who do not require the full multiply throughput of the C6455 model.
