Overview
The TMS320C6670 Multicore Fixed and Floating Point System on Chip, produced by Texas Instruments, is a member of the C66xx SoC family. It is based on TI's KeyStone Multicore SoC Architecture, designed for high-performance applications such as software-defined radio, emerging broadband, and other communications segments. The C6670 integrates four TMS320C66x DSP Core Subsystems, each operating at 1.0 to 1.2 GHz, enabling a combined performance of up to 4.8 GHz. This platform is highly integrated, power-efficient, and easy to use, making it ideal for implementing multi-band, multi-standard waveforms, including proprietary air-interfaces. The C66x CorePac DSP is fully backward compatible with all existing C6000 family of fixed and floating point DSPs.
