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： Resource state sets of a portable computing device are managed. A sleep set of resource states, an active set of resource states and a next-active set of resource states are maintained in memory. A request may be issued for a processor to enter into a sleep state or otherwise change from one application state corresponding to one resource state set to another application state corresponding to another application state set. 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. 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. Providing a next-awake set of resource states that is immediately available to the processor upon a wake-up event helps minimize resource latency.

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.

摘要： 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.
摘要翻译：与应用状态相对应的资源状态集保持在存储器中。对于处于与第一资源状态相对应的第一应用状态中的处理器可以发出请求，该第一应用状态被设置为转换到对应于第二资源状态集合的第二应用状态。基于估计的完成转换的处理时间量来调度开始向第二资源状态集合指示的状态转换资源的开始时间。开始资源状态从由第一资源状态设置指示的状态切换到由第二资源状态集指示的状态的处理。调度进程开始时允许过程完成，以便资源状态在进入第二应用程序状态时立即可用于处理器，有助于最大限度地减少资源等待时间的不利影响。

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.
摘要翻译：一种用于在便携式计算设备（“PCD”）的处理器之间管理对资源的请求的方法和系统包括每个主处理器在诸如消息RAM的存储设备中识别PCD的多个资源。该消息RAM是PCD的一部分。主处理器可以识别消息RAM中的多个资源的期望状态。然后，主处理器可以生成警报，即在消息RAM中已经设置了资源的多个资源和期望状态。在接收到警报之后，控制器可以确定一个或多个先前的请求是否被处理完成。如果是这样，则控制器可以检查消息RAM的内容以识别多个资源并且识别资源的期望状态。如果合适，则控制器可以将所需状态传递给多个资源。
