Joint optimization of processor frequencies and system sleep states

摘要

Systems and methods may provide for identifying a workload cycle for a computing platform, wherein the workload cycle is to include a busy duration and an idle duration. Additionally, platform energy consumption information may be determined for the workload cycle, and a frequency setting may be selected for the busy duration based at least in part on the platform energy consumption information.

1. An apparatus comprising:logic to,
identify a workload cycle for a platform, wherein the workload cycle is to include a busy duration and an idle duration, the busy duration being calculable according to the equation
Tb(fn)=+Tb(f1)*(1−s)+Tb(f1)*s*f1/fn, n=1, . . . , N where Tb is a busy duration, fn is a frequency corresponding to a processor state n and n may vary between 1 and N processor states, and s is a scalability factor, determine platform energy consumption information for the workload cycle, and select a frequency setting for the busy duration based at least in part on the platform energy consumption information.
