Embodiment Construction
[0019] see figure 1 , depicts an illustrative embodiment of a system to generate a gated clock signal and is generally designated 100 . System 100 includes a clock gating unit 102 coupled to a gated circuit 104 . The clock gating unit 102 receives a clock input 106 and a first input 108 . Clock gating unit 102 may also receive one or more additional inputs, such as second input 110 . The clock gating unit 102 provides a gated clock signal 112 to the gated circuit 104 . The clock gating unit 102 includes a clock gating circuit 128 .
[0020] Clock gating circuit 128 contains input logic circuit 114 , which is coupled to internal enable node 107 . Keeper circuit 120 and gating element 122 are also coupled to internal enable node 107 . The keeper circuit 120 includes at least one switching element 128 that is responsive to the gated clock signal 112 . Because switching element 128 is responsive to gated clock signal 112 rather than the input clock signal received at clock ...
