    摘要: A display system is disclosed. The display system has a processor, a memory, a display device, a display controller configured to control the display device, and a bus connecting the processor, the memory, and the display controller. The display system also has a performance monitoring module configured to monitor events that occur on the bus during operation of the display system, and a performance profiling module configured to calculate, based on the monitored events, an available throughput of the processor on the bus. The display system also has a policy manager module configured to determine a refresh rate for the display controller such that a throughput on the bus required by the display controller is less than the calculated available throughput.

    摘要: A processing system may include a performance monitoring unit (PMU), a machine accessible medium, and a processor responsive to the PMU and the machine accessible medium. Instructions encoded in the machine accessible medium, when executed by the processor, may determine whether performance details for the processing system should be collected, based at least in part on a predetermined monitoring policy for the processing system. The instructions may generate performance data for the processing system, based at least in part on data obtained from the PMU. The instructions may determine whether the processing system should be reconfigured, based at least in part on the performance data and a power policy profile for the processing system. The instructions may automatically adjust power consumption of the processing system by using the PMU to reconfigure the processing system. Other embodiments are described and claimed.

    摘要: A mobile electronic communication device power management method and apparatus are disclosed for use in multiple processor hardware schemes having asymmetrical power demands between processors. Upon reaching an long duration idle state, a high-level processor with high power consumption requirements handling low-level system tasks updates a data set shared between processor subsystems containing information necessary to perform such low-level tasks. A proxy software module is initiated on a base-band processor with lower power consumption requirements. The proxy module accesses the shared data set and begins to control low-level system tasks, allowing the high-level processor to enter a dormant low power state. Upon the occurrence of a wake-up event, the high-level processor enters an active state. The shared data set is updated by the proxy software module and the proxy module is terminated. The high-level processor accesses the shared data set and resumes control of low-level system tasks.

    摘要: A disclosed method involves initializing a performance profiler of a processing system. The performance profiler may include performance profile parameters for a power management policy for the processing system. The method also involves retrieving performance metrics for the processing system from a performance monitoring unit (PMU) of the processing system, in response to a determination that performance details should be collected. A current performance state of the processing system may be determined, based at least in part on the performance profile parameters and the performance metrics from the PMU. The current performance state may then be communicated to a policy manager of the processing system. Other embodiments are disclosed and claimed.
