    Abstract: 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.

    Abstract: 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.

    Abstract translation: 基于估计的完成资源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。 在预定的开始时间，开始一个或多个资源的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合指示的状态的过程。 调度资源状态转换过程的开始，这样一来，在进入第二应用程序状态时，可以及时完成资源状态立即可用的进程，从而最大限度地减少资源等待时间的不利影响。 当系统状态和状态之间的转换被精确地测量并存储在便携式计算设备的存储器中时，可以在时间上完成该过程应该完成的时间的计算。

    Abstract: The aspects enable a computing device or microprocessor to determine a low power mode that provides the most 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. Aspects provide a mechanism for determining an optimal low power configuration made up of a set of low power modes for the various resources within the computing device by determining which low power modes are valid at the time the processor enters an idle state, ranking the valid low power modes by expected power savings given the current device conditions, determining which valid low power mode provides the greatest power savings while meeting the latency requirements, and selecting a particular low power mode for each resource to enter.
