DescriptionThe benchmark scores and battery times of mobile CPUs can be improved by choose good Voptz and Ftarget combinations
A ML-based Voptz and Ftarget exploration system called VFOpt has been developed
The RL agent learns how to generate better combinations by evaluating the choices in the previous iteration
The experimental results using a ARM Big CPU shows
VFOpt can improve F at the same operating voltage was improved by 13-80%
VFOpt can also reduce the power at the same operating frequency by up to 25% at the same time
