Overview
The TMS320C6678CYP, produced by Texas Instruments, is a Multicore Fixed and Floating-Point Digital Signal Processor (DSP) based on TI's KeyStone multicore architecture. This device integrates eight TMS320C66x DSP Core Subsystems, each operating at frequencies of up to 1.25 GHz, enabling a cumulative performance of up to 10 GHz. The C6678 is designed for high-performance signal processing applications, including mission-critical systems, medical imaging, test and automation, and various other high-demand scenarios. It is power-efficient, easy to use, and fully backward compatible with all existing C6000 family of fixed and floating point DSPs.
