A 1.25GHz 0.8W C66x DSP Core in 40nm CMOS

The next-generation C66x DSP integrated fixed and floating-point DSP implemented in TSMC 40nm process is presented in this paper. The DSP core runs at 1.25GHz at 0.9V and has a standby power consumption of 800mW. The core transistor count is 21.5 million. The DSP core features 8-way VLIW floating point Data path and a two level memory system and delivers 40 GMACS or 10 GFLOPS floating point MAC performance at 1.25GHz.
