Executive Summary

In the last decade, energy-aware computing has become widespread not only for portable and mobile devices powered by batteries, but also for large systems in which the cost of energy consumption and cooling is substantial. With Dynamic Voltage Scaling (DVS) techniques, processors are capable of performing at a range of voltages and frequencies. Since, energy consumption is at least a quadratic function of the supply voltage (hence CPU speed), the total energy consumption could be minimized by sharing slack time while satisfying the time constraints of the tasks.
