摘要： 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 the resources. At a scheduled start time, a process starts in which the states of one or more resources are switched from states indicated by the first resource state set to states indicated by the second resource state set. Scheduling the process of transitioning resource states 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. This calculation for the time that the process should be completed just in time may be enhanced when system states and transitions between states are measured accurately and stored in memory of the portable computing device.

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： A method and system for dynamically managing a bus within a portable computing device (“PCD”) are described. The method and system include monitoring software requests with a bus manager. The bus manager determines if a software request needs to be converted into at least one of an instantaneous bandwidth value and an average bandwidth value. The bus manager then converts the software requests into these two types of values as needed. The bus manager calculates a sum of average bandwidth values across all software requests in the PCD. With these values, the bus manager may dynamically adjust settings of the bus based on instantaneous or near instantaneous demands from the master devices. This dynamic adjustment of the bus settings may afford more power savings for the PCD during low loads or during sleep states.

摘要： A method and system for managing sleep states of one or more interrupt controllers of processors contained within a portable computing device are described. The method includes a processor defining wake-up interrupt settings in a storage device contained within the portable computing device. This storage device may comprise message random access memory (“RAM”). After wake-up settings have been established in message RAM, a processor may generate an alert that the wake-up settings in the message RAM have been defined. Next, a controller reviews the wake-up interrupt settings in the message RAM for a plurality of interrupt controllers that correspond with a plurality of processors contained within the portable computing device. The controller merges the wake-up settings in the message RAM and then sends the merged wake-up settings to an always-on power manager (“APM”). The APM is responsible for issuing signals to place interrupt controllers of processors into a sleep state.

摘要： A method for selectively scrambling data within a memory associated with a computing device based on data tagging. The computing device may define security domains that are protected. Data generated by an application may be packaged as a data bus transaction having tagging information describing the application and/or the data. The data bus transaction may be transmitted over a bus of the computing device to a memory, such as internal memory, where the computing device may compare the tagging information to stored information describing security domains. When the data is determined to be protected based on the tagging information, the computing device may perform scrambling operations on the data. In an aspect, the tagging information may describe a virtual machine used to execute various applications on a processor. In another aspect, the tagging information may define destination memory addresses or content protection bit values.

摘要： A method and system for managing requests to resources among processors of a portable computing device (“PCD”) includes each master processor identifying a plurality of resources of the PCD in a storage device, such as a message RAM. This message RAM is part of the PCD. A master processor may identify desired states for the plurality of resources in the message RAM. Then, the master processor may generate an alert that the plurality of resources and desired states for resources have been set in the message RAM. After receiving the alert, a controller may determine if one or more previous requests have been processed to completion. If so, then the controller may review the contents of the message RAM to identify the plurality of resources and to identify the desired states of the resources. If appropriate, the controller may pass the desired states to the plurality of resources.

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.
