One of the key areas in which evolvable hardware has shown to excel is in achieving robust analogue and digital electronics. In this paper this domain is investigated further by manipulation of the digital abstraction. Some of the strict requirements of digital gates are relaxed in order to increase the complexity of the functionality available to evolution in order to evolve fault tolerant des...

The authors present a novel virtual reconfigurable architecture (VRA) for realising real-world applications of intrinsic evolvable hardware (EHW) on field programmable gate arrays (FPGAs). The phenotype representation of the proposed evolvable system is based on a two-dimensional function element (FE) network. Compared with the traditional Cartesian genetic programming, the proposed approach in...

This paper overviews Evolvable Hardware (EHW) technology, examining its potential for enhancing survivability and flexibility of future space systems. EHW refers to selfconfiguration of electronic hardware by evolutionary/genetic search mechanisms. Evolvable Hardware can maintain existing functionality in the presence of faults and degradations due to aging, temperature and radiation. It can al...

This paper describes a new technique for the design of Finite Impulse Response (FIR) Filter within an Evolvable hardware framework, using genetic algorithm (GA), aimed at noise cancellation. This implementation aims at reducing the number of generations required to provide time bound optimal filter configuration and to improve the quality of the filter designed. The filter is designed to reconf...

This paper describes circuit evolutionary experiments at extreme low temperatures, including the test of all system components at this extreme environment (EE). In addition to hardening-by-process and hardeningby-design, “hardening-by-reconfiguration ”, when applicable, could be used to mitigate drijts, degradation, or damage on electronic devices (chips) in EE, by using re-con$gurable devices ...

An automatic traffic sign detection system would be important in a driver assistance system. In this paper, an approach for detecting numbers on speed limit signs is proposed. Such a system would have to provide a high recognition performance in real-time. Thus, in this paper we propose to apply evolvable hardware for the classification of the numbers extracted from images. The system is based ...

Traditional approaches to evolvable hardware (EHW), using a direct encoding, have not scaled well with increases in problem complexity. To overcome this there have been moves towards encoding a growth process, however there has not been a great deal of success with these. In this paper we present a morphogenetic EHW system that uses a variable length chromosome on which a gene expression model ...

Evolvable Hardware (EHW) has been proposed as a new method for designing systems for complex real world applications. One of the problems has been that only small systems have been evolvable. This paper indicates some of the aspects in biological systems that are important for evolving complex systems. Further, a divide-and-conquer scheme is proposed, where a system is evolved by evolving small...
