Clock pulses are responsible for over 50% of dynamic power consumption in a synchronous circuit. Clock gating is being used for reduction of power consumption in low power circuits for quite a while now. Adaptive clock gating is most rigorous of them all. Since, gating the clock signals involve additional circuitry there exists a tradeoff between the additional number of gates and the total power consumption of gated clock. In this paper, the authors go through the details of adaptive clock gating technique and the parameters which are to be taken into account while deciding the gating circuitry.
