PCD METHOD AND SYSTEM FOR OPTIMIZING A CORE VOLTAGE LEVEL AND ENHANCING FREQUENCY PERFORMANCE OF INDIVIDUAL SUBCOMPONENTS FOR REDUCING POWER CONSUMPTION WITHIN A PCD

摘要

A method and system for optimizing the core voltage level of a portable computing device ("PCD") and improving the frequency performance of the individual subcomponents is disclosed. A plurality of voltage values for a plurality of subsystems are determined. At least one subsystem is a multiplexed subsystem. Next, a reduced set of voltage values is calculated based on the plurality of voltage values and an optimized voltage level is determined for the shared power domain. The shared power domain is subsequently set to an optimized voltage level. If it is determined that the optimized voltage level exceeds the required voltage level for the at least one multiplexed subsystem when the at least one multiplexed subsystem is executing the plurality of processing engines, then the subset of the plurality of processing engines May be identified to process the workload of the multiplexed system with a more efficient level of power consumption than the overall plurality of processing engines.
