Multiplierless filters have been shown to produce high performance systems with fast signal processing and reduced area. Furthermore, the distributed architecture inherent in multiplierless filters makes it a suitable candidate for fault tolerant design. Alternative approaches to the design of fault tolerant systems have been proposed using evolutionary algorithms (EAs) and the concept of evolvable hardware (EHW). This paper presents an evolvable hardware platform for the automated design and adaptation of multiplierless digital filters. Filters are realised within a dedicated programmable logic array (PLA). The platform employs a genetic algorithm to autonomously configure the PLA for a give set of coefficients. The ability of the platform to adapt to increasing numbers of faults was investigated through the \"evolution\" of a 31-tap low-pass FIR filter. Results show that the functionality of filters evolved on the PLA was maintained despite an increasing number of faults covering up to 25% of the PLA area. Additionally, three PLA initialisation methods were investigated to ascertain which produced the fastest fault recovery times. It was shown that seeding a population of random configuration-strings with the best configuration currently obtained resulted in a 6 fold increase in fault recovery speed over other methods investigated.","PeriodicalId":130694,"journal":{"name":"Proceedings Third NASA/DoD Workshop on Evolvable Hardware.

This involves development of new forms of representation with features such as growth. Shrinking the size of the genotype in effect moves complexity from the genotype representation to the genotype/phenotype mapping. The field of digital evolvable hardware is relatively young but already researchers have not only had to move through different technology platforms i.e. 6200, 4000 and Virtex series, but also evolution friendly features have disappeared. A mass produced evolution friendly reconfigurable platform is not likely to be ahead of us and a newer technology more evolution friendly than traditional reconfigurable platforms is not around the corner. To be able to reuse results and lessons learned from today's technology on tomorrow's technology and exploit the power of evolution, one solution is to provide a virtual evolution friendly reconfigurable platform which may be mapped onto a given technology. We propose a two stage genotype/phenotype mapping using our virtual evolvable hardware FPGA us the bridge. The two stages simplify the genotype/phenotype transition at the same time as the virtual evolvable hardware FPGA bridge provides a more evolution friendly platform, further reducing the complexity of the genotype representation.","PeriodicalId":130694,"journal":{"name":"Proceedings Third NASA/DoD Workshop on Evolvable Hardware.
