WebFeb 18, 2014 · These are call integrated clock gating cells or ICG. There are two commonly used ICG cell types. Using AND gate with high EN. The following design uses a negative edge triggered latch to synchronize the … In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit is not in use or ignores clock signal. Clock gating saves power by pruning the clock tree, at the cost of adding more logic to a circuit. Pruning the clock disables portions of the circuitry so that the flip-flops in them do not have to switch states. Switching states consumes power. When not b… onoffcharge2安装不上
