Overview
The TMS320C6414T, part of the TMS320C64x™ family, is a high-performance fixed-point Digital Signal Processor (DSP) developed by Texas Instruments. This DSP is based on the second-generation VelociTI™ very-long-instruction-word (VLIW) architecture, specifically the VelociTI.2™ extensions. It is designed to deliver exceptional performance, making it an excellent choice for wireless infrastructure applications and other high-demand DSP tasks. The C64x™ devices are code-compatible with the C62x™ and offer a range of features that enhance their operational flexibility and numerical capability.
