Abstract
A method and device for setting a processor performance profile for a processor that is unable to directly measure voltage supplied by a voltage regulator includes determining a voltage requested of the voltage regulator and determining a first characteristic of a first portion of the electrical component. The first characteristic is one of power consumed by the first portion of the electrical component and load presented by the first portion of the electrical component. A first current is then determined by using the first voltage, the first characteristic, and a known relationship therebetween. A third voltage that is an estimate of the voltage supplied by the voltage regulator is then determined by comparing the first current to load line characteristics of the electrical component. The third voltage is then used to manage performance of the processor.
