Abstract
An integrated circuit may have separate power control for a number of different functional units. Ancillary to some of the functional units may be an activity detector and power control unit which monitors input to its functional unit to determine when the functional unit will be inactive. When an activity detector and power control unit determines that a particular functional unit is or will be inactive, it may disable power to its functional unit while the functional unit is inactive. When activity detector and power control unit determines that activity will resume for its functional unit, it enables power to its functional unit. Thus, the activity detector and power control unit for each such functional unit functions to control power to its respective functional unit so that during periods of inactivity, inactive functional units are powered down to reduce the overall static and/or dynamic power consumption for the integrated device.
