ABSTRACT:
A multi-processing system2measures the degree of parallelism achieved in executing program instructions and uses this to dynamically control the clock speeds and supply voltage levels applied to different processor cores4, 6so as to reduce the overall amount of energy consumed by matching the processing performance achieved to the clock speeds and voltage levels used.
