This work demonstrates a dual-core RISC-V system-on-chip (SoC) with integrated fine-grain power management. The 28-nm fully depleted silicon-on-insulator (FD-SOI) SoC integrates switched-capacitor voltage converters and 4-Gb/s off-chip serial links. The SoC runs applications with operating system support on dual RISC-V Rocket cores with vector accelerators. Runtime monitoring of microarchitectural counters allows prediction of future compute intensity, enabling the voltage state of the managed core to be adjusted quickly to optimize energy efficiency without sacrificing overall performance.
