Abstract :
A processor consumes far less energy running tasks requiring a low supply voltage than it does executing high-performance tasks. Effective voltage-scheduling techniques take advantage of this situation by using software to dynamically vary supply voltages, thereby minimizing energy consumption and accommodating timing constraints
