    摘要: 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.

    摘要: In a portable computing device having a node-based resource architecture, a first or distributed node controlled by a first processor but corresponding to a second or native node controlled by a second processor is used to indirectly access a resource of the second node. In a resource graph defining the architecture each node represents an encapsulation of functionality of one or more resources, each edge represents a client request, and adjacent nodes represent resource dependencies. Resources defined by a first graph are controlled by the first processor but not the second processor, while resources defined by a second graph are controlled by the second processor but not the first processor. A client request on the first node may be received from a client under control of the first processor. Then, a client request may be issued on the second node in response to the client request on the first node.

    摘要: A method and system for managing resources of a portable computing device is disclosed. The method includes receiving node structure data for forming a node, in which the node structure data includes a unique name assigned to each resource of the node. A node has at least one resource and it may have multiple resources. Each resource may be a hardware or software element. The method also includes receiving marker data and creating a marker. A marker includes a legacy element such as a hardware or software element. The system includes a framework manger which handles the communications between existing nodes and markers within a node architecture. The framework manager also logs activity of each resource and marker by using its unique name. The framework manager may send this logged activity to an output device, such as a printer or a display screen.

    摘要: A method and system for maximizing a quality of service (“QoS”) level in a portable computing device (“PCD”) by preempting the generation of thermal energy in excess of a threshold are disclosed. The method includes receiving a workload request for a processing component within the PCD. A processing component is selected for allocation of the workload based on thermal factors associated with the processing component. Thermal factors may comprise data indicative of real-time thermal energy generation near the processing component, predictive data derived from known characteristics of heat producing components that are physically proximate to the processing component, queued workload burdens for the processing component, etc. A processing component is selected for allocation of the workload based on the thermal factors. By leveraging the thermal factors to allocate workloads, thermal generation can be proactively managed such that reliance on reactive thermal mitigation techniques, which negatively impact QoS, can be reduced.
