Invertible logic is a method of reversible computing that can propagate a circuit signal backward from outputs. For example, not only multiplication (forward operation) but also division and factorization (backward operation) can be performed by this circuit style of a single multiplier. Currently, invertible logic has been able to realize only small-scale circuits. In this paper, we design larger-scale circuits than that reported conventionally, using stochastic computing. Furthermore, we also verify the performance of invertible logic using three different multipliers.
