Abstract:
A clock gating system and method is disclosed. In a particular embodiment, the system includes an input logic circuit having at least one input to receive at least one input signal and having an output at an internal enable node. A keeper circuit includes at least one switching element that is responsive to a gated clock signal and is coupled to the internal enable node to selectively hold a logical voltage level at the internal enable node. The system further includes a gating element responsive to an input clock signal and to the logical voltage level at the internal enable node to generate the gated clock signal.
