Abstract

A power supply system of an electronic system is dynamically switchable upon fluctuating demand for operational power. The power supply is capable of providing multiple voltage values to an electronic system which is capable of utilizing multiple logical voltage values. The power utilized by the electronic system is further controlled by varying the frequency at which the electronic system operates. Power is conserved by operating at a lower voltage and frequency and is optimally utilized upon demand by dynamically switching to operate at higher voltages and frequencies for the duration of the increased power demand. Temporary peak power greater than average operational power may be attained.
