Abstract
A method for automatically transitioning a processor to another performance level in a demand-based system. One embodiment of the invention provides for the automatic adjustment of processor frequency while preserving system responsiveness. The performance-level policy algorithm detects increased processor utilization quickly enough that transition to a higher performance level is comparable to maximum system performance. The performance-level policy algorithm delays processor transition to a lower performance level so that quick reversals in demand do not precipitate unnecessary transitioning.
