ABSTRACT:
A voltage identifier (VID) sorting system is provided that optimizes processor power and operating voltage guardband at a constant processor frequency. The VID sorting system determines a voltage versus current curve for the processor. The VID sorting system then uses the voltage versus current characteristics to calculate the power for each VID to determine an acceptable range of VIDs within the maximum power criteria. The VID sorting system then tests VIDs in the range and selects a VID from the range to optimize for minimum power and/or maximum voltage guardband at a constant processor frequency.
