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 is determined for a plurality of subcomponents within the PCD. Next, a reduced set of voltage values may be calculated with a voltage aggregator based on the plurality of voltage values. An optimized voltage level for a shared power domain may then be determined by a voltage optimizer within the PCD from the reduced set of voltage values. A shared power domain may then be set to the optimized voltage level. Subsequently, an 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.

Method and system for optimizing a core voltage level and enhancing frequency performance of individual subcomponents for reducing power consumption within a PCD

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.

A portable computing device includes a modem and an application processor communicatively coupled by a data bus. The modem communicates a target data throughput in accordance with an identified data call. In response, the application processor determines whether an adjustment of an interrupt latency threshold is warranted to support the target data throughput identified by the modem. Otherwise, the application processor executes no such adjustment. In addition, the modem requests a desired performance of an application processor resource. In response, the application processor adjusts a control input of the application processor controlled resource. A change in a present data transfer session triggers the modem to communicate a revised target data throughput and/or a revised request for a desired performance of an application processor resource.
