A reversible finite automaton (RFA) is a backward deterministic automaton, i.e., it can uniquely retrace its move sequence if the inverse sequence of its outputs is given. In this paper, we show a simple method to construct an RFA from Fredkin gates, which are reversible and bit-conserving logic gates, and unit wires (unit delays). The resulting circuit obtained by this method is "garbage-less" in the sense that it has no inputs to which constants must be supplied nor outputs from which garbage signals are put out. We also show that a one-dimensional reversible partitioned cellular automaton, which are known to be computation universal, can be constructed from Fredkin gates and unit wires as a closed (thus garbage-less) infinite circuit.
