ABSTRACT:
Methods and apparatus are disclosed to control power consumption within a processor. An example processor disclosed herein comprises an instruction retirement unit; a first set of functional blocks to process a first set of instructions having a first instruction type; a second set of functional blocks to process a second set of instructions having a second instruction type; and a controller to enable the first set of functional blocks to process an instruction allocated to the instruction retirement unit if the type of the instruction is the first type, and to disable the first set of functional blocks after the instruction is retired by the instruction retirement unit.
