METHOD AND SYSTEM FOR OPTIMIZING A CORE VOLTAGE LEVEL AND OPERATING FREQUENCY OF INDIVIDUAL SUBCOMPONENTS FOR REDUCING POWER CONSUMPTION WITHIN A PORTABLE COMPUTING DEVICE

摘要

A method and system are disclosed for optimizing a core voltage level of a portable computing device (“PCD”) and improving the frequency performance of individual subcomponents. A plurality of voltage values are determined for a plurality of subcomponents in the PCD. Next, the reduced set of voltage values may be calculated with a voltage aggregator based on the plurality of voltage values. An optimized voltage level for the shared power domain may then be determined by a voltage optimizer in the PCD from the reduced set of voltage values. Next, the shared power domain may be set to an optimized voltage level. Subsequently, the operating frequency of each subcomponent may be optimized with a frequency performance enhancer based on the optimized voltage level. An optimal power collapse duration may also be calculated by the frequency performance enhancer and set for each subcomponent from the optimal frequency.
