Abstract
A circuit arrangement maintains power usage prediction information for one or more functional units in branch prediction logic for a processing unit such that the power consumption of a functional unit may be selectively reduced in association with the execution of branch instructions when it is predicted that the functional unit will be idle subsequent to the execution of such branch instructions.
