Resource state sets corresponding to the application states are maintained in memory. A request may be issued for a processor operating in a first application state corresponding to the first resource state set to transition to a second application state corresponding to the second resource state set. A start time to begin transitioning resources to states indicated in the second resource state set is scheduled based upon an estimated amount of processing time to complete transitioning. A process is begun by which the states of resources are switched from states indicated by the first resource state set to states indicated by the second resource state set. Scheduling the process to begin at a time that allows the process to be completed just in time for the resource states to be immediately available to the processor upon entering the second application state helps minimize adverse effects of resource latency.

System for minimizing resource latency between processor application states in a portable computing device by scheduling resource state set transitions

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.
