Abstract: Redundancy is a critical component to the design of fault tolerant systems; both hardware and software. This paper explores the possibilities of using evolutionary techniques to first produce a processing system that will perform a required function, and then consider its applicability for producing useful redundancy that can be made use of in the presence of faults, ie is it fault tolerant? Results obtained using Evolutionary Strategies to automatically create redundancy as part of the "design" process are given. The experiments are undertaken on a Virtex FPGA with intrinsic evolution taking place. The results show that not only does the evolutionary process produce useful redundancy, it is also possible to reconfigure the system in real-time on the Virtex device.
