Evaluating the effects of reducing voltage margins for energy-efficient operation of MPSoCs
Abstract
This letter assesses the energy efficiency gains available by aggressively reducing voltage guardbands on a commercial RISC-V Multi-Processor System-on-Chip (MPSoC). Standard voltage margins ensure reliability but severely limit energy efficiency, a critical
