  • Abstract
    A locally asynchronous, globally synchronous (LAGS) system with data/instruction grain control is presented for the optimization of power supply voltage, speed performance, PVT and noise tolerance. A LAGS CPU with on-chip DC-DC converter that occupies 250times60mum2 in 90nm CMOS has 0.98V to 0.68V VDD control with 50ns/85ns transition time and a speedtracing accuracy of 5%
