Abstract
A system and method for adaptive activity management of on-chip voltage regulators based upon the workload information is provided to force each on-chip regulator to operate in its most power-efficient load current. In the proposed regulator-gating technique, regulators are adaptively turned ON when the current demand is high and turned OFF when the current demand is low to improve the voltage conversion efficiency. With the proposed regulator-gating system and method, the overall voltage conversion efficiency from the battery or off-chip power supply to the output of the on-chip voltage regulators experiences an approximately 3 times improvement over the prior art techniques.
