ABSTRACT:
A power consumption control apparatus and method for an asynchronous system is provided that reduces power consumption by selecting one of a plurality of power consumption levels for the system. The power consumption levels can be determined based on work load requirements of the system and can be implemented for the system or portions thereof using a single block of the system. The asynchronous system includes a plurality of intercoupled functional units and a power control circuit coupled to a selected one of the plurality of functional units to determine at least one of a first and a second operating speed of a selected functional unit.
