We introduce a scheme to obtain key logic-gate structures, using synchronization of nonlinear systems. We demonstrate the idea explicitly by numerics and experiments on nonlinear circuits. A significant feature of this scheme is that a single nonlinear drive-response circuit can be used to flexibly yield the different logic gates, and switch logic behavior by small changes in the parameter of the response system; so the response system can act as a “logic output controller.” Thus this scheme may help to construct dynamic general-purpose computational hardware with reconfigurable abilities.
