Figure 3.3.7 (a) illustrates an LSSD cell block diagram, and Figure 3.3.7 (b) shows the LSSD cell's gate level schematic. Multiple clocks A, B, and C control the latches. In normal operating mode, clock C clocks data into L1 from the data input and ... 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… flood proof homes
