Implementation of Logical Operations on a Domino Substrate
Simon O’Keefe
This paper presents some simple ideas about domino gates. Domino gates are implementations of logical operations using toppling dominoes to represent the movement of information (bits). The actively toppling domino represents a logic one, and absence of toppling represents logic zero. The domino model can be used as a representation of single-shot wave gates in unconstrained media, such as sub-excitable Belousov-Zhabotinsky reactors. On a practical note, they are slightly easier to set up and use than collision logic models using ‘billiard balls’.
