Overview
The TMS320C6454BGTZA is a high-performance fixed-point digital signal processor (DSP) from Texas Instruments, part of the C64x+ 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 of the TMS320C6455 who do not require the full multiply throughput of the C6455.
