(ACTIVE) Multicore Fixed and Floating-Point Digital Signal Processor


Functional diagram


The TMS320C6678 Multicore Fixed and Floating Point Digital Signal Processor is based on TI's KeyStone multicore architecture. Integrated with eight C66x CorePac DSPs, each core runs at 1.0 to 1.25 GHz enabling up to 10 GHz. The device supports high-performance signal processing applications such as mission critical, medical imaging, test, and automation. The C6678 platform is power efficient and easy to use. The C66x CorePac DSP is fully backward compatible with all existing C6000 family of fixed and floating point DSPs.
