Overview
The TMS320C6414T, specifically the TMS320C6414TBGLZA7, is a high-performance fixed-point Digital Signal Processor (DSP) from Texas Instruments. It is part of the TMS320C64x™ DSP generation within the TMS320C6000™ DSP platform. This DSP is based on the second-generation VelociTI™ very-long-instruction-word (VLIW) architecture, known as VelociTI.2™, which enhances performance and parallelism. The C64x devices are renowned for their operational flexibility, combining the capabilities of high-speed controllers and array processors. They are particularly suited for wireless infrastructure, multichannel, and multifunction applications due to their high performance and cost-effectiveness.
