  • Patent number: 4873456
    Abstract: A state element having a pair of parallel-connected, inversely-enabled latches forms the basic state-machine building block. A flip-latch is formed by combining this basic element with a multiplexer for selectively outputting alternate outputs of the latches. A litch-latch is formed by using the basic element alone with the two inputs fed from one of a pair of identical logic elements and feeding back the output from each latch to the logic element from which the input is not received. Other outputs of the logic elements are input into a multiplexer for alternately selecting the outputs from the respective logic elements to be the state machine output. These state elements function similarly to a flip-flop but generally produce less propagation delay and require a lower clocking signal frequency for a given state frequency.
