Abstract
An apparatus for on-demand power management including a system controller, a clock domain manager coupled to the system controller and a power distribution manager coupled to the system controller. The system controller monitors a processing demand in a processing system. The clock domain manager provides one or more clock frequencies and, in response to the processing demand, switches between a first set of clock frequencies and a second set of clock frequencies without halting the processing system. The power distribution manager provides one or more operating voltages and, in response to the processing demand, switches between a first set of voltages and a second set of voltages without halting the processing system.
