Summary:A processor and method are disclosed. In one embodiment the processor includes a prefetch buffer that stores macro instructions. The processor also includes a clock circuit that can provide a clock signal for at least some of the functional units within the processor. The processor additionally includes macro instruction decode logic that can determine a class of each macro instruction. The processor also includes a clock management unit that can cause the clock signal to remain in a steady state entering at least one of the units in the processor that do not operate on a current macro instruction being decoded.
