Software energy reduction techniques for variable-voltage processors
Takanori Okuma, Hiroto Yasuura, Tohru Ishihara · IEEE Design & Test of Computers · 2001
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.
