One embodiment of the present invention provides a domino logic circuit that operates asynchronously. This domino logic circuit contains a pipeline comprised of a number of stages of domino logic, including a present stage that receives one or more inputs from a prior stage and that generates one or more outputs for a next stage. The present stage includes a control circuit that is configured to ensure that the present stage enters a precharging state before entering an evaluation state-in which one or more inputs of the present stage are used to generate one or more outputs. This control circuit operates by receiving a prior control signal from the prior stage and sending a present control signal to the next stage. During this process, the control circuit ensures that a minimum cycle time between successive evaluation states is six gate delays.
