Problems solved by technology

And every subcomponent of a PCD (e.g. camera and mobile display in a battery-powered PCD) ultimately consumes power and contributes to the overall power consumption and performance of the PCD
[0005] One problem with conventional PCDs is that the highest voltage expected from the subassembly of the PCD with the heaviest workload determines the voltage levels of the entire PCD as well as its other subassemblies
The increase in voltage of these other sub-components without a heavy workload compared to the image processor with a heavy workload results in significant current leakage from these lightly Significant power loss from components

Abstract

A method and system for optimizing a core voltage level of a portable computing device (PCD) and enhancing frequency performance of individual subcomponents are disclosed. A plurality of voltage values for a plurality of subsystems is 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 a shared power domain. The shared power domain is subsequently set to the optimized voltage level. If the optimized voltage level is determined to exceed a required voltage level for the at least one multiplexed subsystem when it is running the plurality of processing engines, a subset of the plurality of processing engines may be identified to process a workload of the multiplexed system at a more efficient level of power consumption than the full plurality of processing engines.
