Method and apparatus for asynchronously controlling domino logic gates

摘要

One embodiment of the present invention provides a domino logic circuit that operates asynchronously. This domino logic circuit includes a number of stages, including a present stage that receives one or more inputs from a prior stage and generates one or more outputs for a next stage. It also includes a control circuit that ensures that the present stage enters a precharging state before entering a subsequent evaluation state in which one or more inputs of the present stage are used to generate one or more outputs. This control circuit receives a prior control signal from the prior stage and sends a present control signal to the next stage
