ABSTRACT:
An instruction cycle is determined from instructions stored in a cache, where the instruction cycle represents the sequence of instructions predicted to be executed by the processing device that are resident in the cache. The duration of the instruction cycle is estimated and one or more components of the processing device that are not expected to be used during the instruction cycle may be suspended for a portion or all of the duration. The components may be suspended by, for example, clock gating or by isolating the components from one or more power domains.
