摘要： A method and system for managing requests among resources within a portable computing device include a scheduler receiving data from a client for scheduling a plurality of requests. Each request identifies at least one resource and a requested deadline. Next, data from the client is stored by the scheduler in a database. The scheduler then determines times and a sequence for processing the requests based on requested deadlines in the requests and based on current states of resources within the portable computing device. The scheduler then communicates the requests to the resources at the determined times and according to the determined sequence. The scheduler, at its discretion, may schedule a request after its requested deadline in response to receiving a new request command from a client. The scheduler may allow a sleep set corresponding to a sleep processor state to power off a processor.

摘要： The aspects enable a computing device or microprocessor to determine a low-power mode that maximizes system power savings by placing selected resources in a low power mode while continuing to function reliably, depending upon the resources not in use, acceptable system latencies, dynamic operating conditions (e.g., temperature), expected idle time, and the unique electrical characteristics of the particular device. The various aspects provide mechanisms and methods for compiling a plurality of low power resource modes to generate one or more synthetic low power resources from which can be selected an optimal low-power mode configuration made up of a set of selected synthetic low power resources.

摘要： A method and system for tracking and selecting optimal power conserving modes of a PCD includes detecting enablement or disablement of a reduced power mode and detecting one of a new and a change in a latency restriction. Next, a low power mode which has a minimum entry and exit latency may be identified. Then, it may be determined if a lowest latency restriction is less than the minimum entry and exit latency. A function pointer may be adjusted based on the output of the determining step. The function pointer may reference a halt state and a reduced power state for the PCD. Then, conditions favorable for at least one of an idle state and a reduced power mode of the PCD may be assessed. If conditions are favorable for an idle state or a reduced power mode for the PCD, then status of the function pointer may be read.
