Abstract

This paper presents a novel Energy-Aware Compilation(EAC) framework that can estimate and optimize energyconsumption of a given code taking as input the architecturaland technological parameters, energy models, andenergy/performance constraints. The framework has beenvalidated using a cycle-accurate architectural-level energysimulator and found to be within 6% error margin whileproviding significant estimation speedup. The estimationspeed of EAC is the key to the number of optimization alternativesthat can be explored within a reasonable compilationtime.
