  • Method, apparatus, and system for energy efficiency and energy conservation by mitigating performance variations between integrated circuit devices
    Patent number: 9753516
    Abstract: According to one embodiment of the invention, an integrated circuit device comprises one or more processor cores and a control unit coupled to the processor core(s). The control unit is adapted to control an operating frequency of at least one processor core based on an estimated activity level in lieu of a power level. The estimated activity level differing from an estimated power level by being independent of leakage power and voltage characteristics particular to that integrated circuit device.
