CONTROLLING A PROCESSOR RESOURCE BASED ON A COMPILE-TIME PREDICTION OF NUMBER OF INSTRUCTIONS-PER-CYCLE THAT WILL BE EXECUTED ACROSS PLURAL CYCLES BY THE PROCESSOR

A method, for use in a processor, includes estimating a number of instructions-per-cycle that will be executed by the processor based on static compile-time information extracted during compilation, and controlling a resource of the processor based on the estimated number of instructions-per-cycle. The resource may be a component of the processor that is controlled by throttling or deactivating the component.
