Abstract
A clock gating circuit is disclosed. The clock gating circuit includes an input circuit configured to receive an enable signal and clock enable circuitry configured to receive an input clock signal. The clock gating circuit also includes a latch that captures and stores an enabled state of the enable signal when the enable signal is asserted. An output circuit is coupled to the latch, and provides an output signal corresponding to a state of the clock signal when the latch is storing the enabled state. The clock gating circuit is arranged such that, when the latch is not storing the enabled state, no dynamic power is consumed responsive to state changes of the input clock signal.
