Direction-Reversible Self-Timed Cellular Automata for Delay-Insensitive Circuits

2016-09-16T14:24:29Z (GMT) by Irek Ulidowski Daniel Morrison
We introduce a new Self-Timed Cellular Automaton capable of simulating reversible delay-insensitive circuits. In addition to a number of reversibility and determinism properties, our STCA exhibits direction-reversibility, where reversing the direction of a signal and running a circuit forwards is equivalent to running the circuit in reverse. We define also several extensions of the STCA which allow us to realise three larger classes of delay-insensitive circuits, including parallel circuits. We then show which of the reversibility, determinism and direction-reversibility properties hold for these classes of circuits
