Inspired by the basic processes of molecular biology, our previous studies resulted in defining a configurable molecule implementing self-replication and self-repair mechanisms made up of simple processes. The goal of our paper is to add error detection features to the molecule in order to make it able to perform also built-in self-test mechanisms. The hardware description of the molecule with all its self-organizing mechanisms leads to the simulation of an image processing array dedicated to thresholding and boolean operations.
