A honeycomb development architecture for robust fault-tolerant design

Andy M. Tyrrell, Hong Sun

Research output: Chapter in Book/Report/Conference proceedingConference contribution


A new hardware developmental model that shows strong robust transient fault-tolerant abilities and is motivated by embryonic development and a honeycomb structure is presented. Cartesian Genetic Programming (CGp) is used to evolve the cell structure. A pattern formation problem is realised by cells with identical evolved structures. The pattern is shown to recover from various kinds of transient faults. The fault-tolerance of this structure is not designed, but evolved under selective pressure in an environment of chemicals and states. The increased interactions between cells, brought about by the honeycomb structure, speeds up the evolutionary process and simplifies the structure of the evolved circuits compared to previous embryonic systems.
