Abstract: Systems and methods may provide for making a power efficiency determination at runtime based on one or more runtime usage notifications and scheduling a workload for execution on a hardware accelerator if the power efficiency determination indicates that execution of the workload on the hardware accelerator will be more efficient than execution of the workload on a host processor. Additionally, the workload may be scheduled for execution on the host processor if the power efficiency determination indicates that execution of the workload on the host processor will be more efficient than execution of the workload on the hardware accelerator. In one example, making the power efficiency determination includes applying one or more configurable rules to at least one of the one or more runtime usage notifications.

Abstract: 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.

Abstract: A row-wise technique may be utilized for determining a fractional matching block in a motion estimation vector algorithm. By interpolating and calculating a sum of absolute differences on a row-wise basis, a more efficient algorithm may be implemented. On a row-by-row basis, the corresponding interpolated values are updated and those values, once updated, may be compared to determine the best match among the potential fractional matching blocks. As a result, a fractional matching block may be identified to determine the motion vector to a greater degree of accuracy.
