Abstract
Clock gating saves dynamic power by shutting off a subtree of clock network during the idle state of the driven logic blocks. This paper proposes a new clock gating methodology based on a precise power saving analysis to overcome the ineffectiveness of the conventional logic structure based clock gating. Two new features exploited in our proposed clock gating are (i) the multiplexer selection signal probability that a flip-flop with multiplexer feedback loop receives a new input and (ii) the joint probability of selection signals that two flip-flops with different multiplexor selection signals both receive new inputs at the same clock cycle.
