摘要： A method and system for dynamically creating and servicing master-slave pairs within and across switch fabrics of a portable computing device ("PCD") are described. The system and method includes receiving a client request comprising a master-slave pair and conducting a search for a slave corresponding to the master-slave pair. A route for communications within and across switch fabrics is created and that corresponds to the master-slave pair. One or more handles or arrays may be stored in a memory device that correspond to the created route. Next, bandwidth across the route may be set. After the bandwidth across the newly created route is set, the client request originating the master-slave pair may be serviced using the created route. Conducting the search for the slave may include comparing unique identifiers assigned to each slave in a master-slave hierarchy. The search within and across switch fabrics may also include reviewing a fabric route check table for slaves that can be interrogated within a switch fabric.

摘要： Systems and methods for optimizing performance scaling algorithms designated for operation on a mobile device are disclosed. A system memory includes program, use case, and results stores in addition to test logic. The program store contains a set of programs defined by the combination of a performance scaling algorithm and a set of parameters. The use case store contains information that identifies expected tasks to be performed by end users of the mobile device over time. The results store organizes a respective merit value determined after each of the set of programs has been executed for tasks defined by each use case. When executed, the test logic adjusts the mobile device and associates a select program for each of the use cases in response to the stored merit values. The merit values are determined as a function of a performance metric and a power metric.

摘要： A method and system for determining optimal operating parameters for conserving power of a portable computing device may include plotting a hypersurface in a coordinate system. The method includes defining one or more axes in a coordinate system, such as a Cartesian coordinate system, that impact power consumption of a PCD and which may be held as constants when applied as workloads on CPU. Then, at least one axis is identified as an unknown or variable which may be optimized for power consumption. After the hypersurface containing optimized values is created for various workload scenarios for the PCD, workloads corresponding to the synthetic workloads described above are applied to the PCD. Workload predictors, like a DCVS algorithm, are executed by the PCD and are observed and compared to the hypersurface. Parameters for the workload predictor may be adjusted based on the values from the hypersurface.

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.
