Abstract

The concept of energy aware software is introduced. A simple energy model for software is presented that separates the switching and leakage components and predicts its total energy consumption with less than 5% error for a set of benchmark programs. The experiments have been performed on the StrongARM SA-1100 microprocessor. A mathematical model for the total leakage current has also been proposed and it has been shown that they can account for about 10% of the energy dissipation for low threshold voltage microprocessors and, assuming continuous operation, the leakage energy fraction gets significantly higher for lowest duty cycle
