clock gating

Clock gating and power gating are power management methods for reducing the power consumption of functional units.

Clock gating can be used to reduce the power consumption of mobile computers, notebooks, netbooks or other mobile devices, thereby extending their operating time.

Clock gating reduces power consumption by switching off the clock frequency of functional units that are temporarily no longer needed. The clock gating function is mainly used in registers where the clock pulse is faded out via a gate.
