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.

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 and system for managing sleep states of a portable computing device are described. They include maintaining a sleep set of resource states and an active set of resource states in memory. A request may be issued for a processor to enter into a sleep state. This causes a controller to review a trigger set to determine if a shut down condition for the processor matches one or more conditions listed in the trigger set. Each trigger set may comprise a “trigger event” that may allow a controller to select a specific resource set which is desired by a particular processor based on a trigger event detected by a system power manager. If a trigger set matches a shut down condition, then switching states of one or more resources in accordance with the sleep set may be made by the controller without using a software handshake.
