TMS320C6657-EVM Custom Hardware and
Board Design Services

The TMS320C66x+™ DSPs are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. The C6657 device is based on the KeyStone architecture developed by Texas Instruments (TI). The C66x+ devices are code-compatible to previous devices that are part of the C6000™ DSP platform.

Developed by eInfochips, the C6657 Lite EVM with AMC Form-Factor enables developers to immediately start evaluating TMS320C6657 processor and begin building application around it especially those demanding high-performance computation like video & telecom infrastructures, medical and imaging.


(TMS320C6657 Lite Evaluation Module) The TMDSEVM6657L EVM comes with XDS100 onboard emulation capability. In addition, an external emulator via JTAG emulation header can also be used.


TMS320C6657 Lite Evaluation Module with XDS560V2 Emulation The TMDSEVM6657LE EVM comes with onboard XDS560V2 emulation capability. The included XDS560 Mezzanine Card is mounted on the TI 60-pin JTAG emulation header.
