Overview
The TMS320C6672 is a high-performance, dual-core digital signal processor (DSP) from Texas Instruments, based on the KeyStone multicore architecture. This device is designed for applications requiring high computational power and efficiency, such as mission-critical systems, high-performance computing, communications, audio, video infrastructure, and more. The TMS320C6672 features two C66x DSP core subsystems, each capable of operating at speeds of up to 1.5 GHz, providing 48 GMACs/core for fixed-point operations and 24 GFLOPS/core for floating-point operations. It is fully backward compatible with all existing C6000 family fixed and floating-point DSPs, ensuring software portability and shortened development cycles.
