Abstract

A method for on-demand power management monitors a processing demand in a processing system operating at a first set of voltages and frequencies and generates a second set of voltages and frequencies in response to the processing demand. The method switches from the first set of voltages and frequencies to the second set of voltages and frequencies without halting the processing system.
