The TMS320C6670 Multicore Fixed and Floating Point System on Chip is a member of the C66xx SoC family based on TI's new KeyStone Multicore SoC Architecture designed specifically for high performance applications such as software defined radio, emerging broadband and other communications segments. Integrated with four C66x CorePac DSPs, each core runs at 1.0 to 1.20 GHz enabling up to 4.8 GHz. Hardware acceleration provides a highly integrated, power efficient and easy to use platform for implementing a combination of multi-band, multi-standard waveforms, including proprietary air-interfaces. The C6670 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.
