Patent ID: 8874949

Claim:
An apparatus for efficient energy consumption comprising: a processor a controller coupled with the processor to receive a temperature measurement corresponding to a current temperature of the processor, determine an adjustment to a voltage being applied to the processor based at least in part on the temperature measurement and a plurality of internal limits of the processor, wherein the determined adjustment to the voltage is based on an inverse temperature dependence relationship between at least one of an operating frequency and a voltage of the processor, and temperature, wherein the voltage to the processor is increased as temperature decreases and wherein the controller to determine separate voltage adjustment values for each of the plurality of internal limits of the processor comprising a transistor speed voltage minimum and a processor array voltage minimum and choose a single voltage adjustment from among the separate voltage adjustment values to be provided to a voltage regulator interface, and provide the determined adjustment to the voltage to voltage regulator interface; and a voltage regulator coupled to the voltage regulator interface to provide voltage to the processor.
