Abstract

We extend the description of a discrete-time cellular neural network, depicting the behaviour of both cellular and morphological processors, to any type of dual-rail processors. We show that a system with two arrays of differential pairs of transceivers can be treated as a two-layer cellular network and that it can perform morphological and rank order filter operations. As an illustration we built and tested a dual-rail processor composed of arrays of GaAs optical thyristor differential pairs and highlight experimental results on median filtering.
