WebIn electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat [1]) is an electronic logic signal ( voltage or current) which … 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… WebIn general, clock latency (or clock insertion delay) is defined as the amount of time taken by the clock signal in traveling from its source to the sinks.
