Fixed and Floating Point Digital Signal Processor - TMS320C6657

TMS320C6657 (ACTIVE)

Fixed and Floating Point Digital Signal Processor

Description

The TMS320C6657/55 Multicore Fixed and Floating Point Digital Signal Processors are based on TI's KeyStone multicore architecture. The C6657 is integrated with two C66x DSP CorePacs running at 0.85, 1.0 or 1.25 GHz. The C6655 contains one C66x DSP CorePac running at 1.0 or 1.25 GHz. These devices support high-performance signal processing applications such as mission critical, medical imaging, test, and automation. The C6657/55 platform is power-efficient and easy-to-use. The C66x CorePac DSP is fully backward compatible with all existing devices in the C6000 family of fixed and floating point DSPs.
