摘要： An embodiment of the present invention includes a method to analyze processor performance. A processor is saturated with a workload. The processor has a specified operating frequency and a thermal throttling range from a minimum throttling state to a maximum throttling state. Events are sampled for a pre-determined time interval at a sampling rate during the workload. An effective processor frequency is calculated using the sampled events, the pre-determined time interval, and the sampling rate.

摘要： Technologies for transferring offloading or on-loading data or tasks between a processor and a coprocessor include a computing device having a processor and a sensor hub that includes a coprocessor. The coprocessor receives sensor data associated with one or more sensors and detects events associated with the sensor data. The coprocessor determines frequency, resource usage cost, and power state transition cost for the events. In response to an offloaded task request from the processor, the coprocessor determines an aggregate load value based on the frequency, resource usage cost, and power state transition cost, and determines whether to accept the offloaded task request based on the aggregate load value. The aggregate load value may be determined as an exponential moving average. The coprocessor may determine whether to accept the offloaded task request based on a principal component analysis of the events. Other embodiments are described and claimed.
