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.
