Abstract :
Dynamic voltage and frequency scaling of the CPU has been identified as one of the most effective ways to reduce energy consumption of a program. This paper discusses a compilation strategy that identifies scaling opportunities without significant overall performance penalty. Simulation results show CPU energy savings of 3.97%-23.75% for the SPECfp95 benchmark suite with a performance penalty of at most 2.53%
