A Signal Processing Architecture based on Evolving Digital Logic Gates

Abstract — Evolvable Hardware (EHW) is a new method for designing electronic circuits. In this paper, the scheme is applied for the design of a novel digital signal processing architecture. It is based on incremental evolution of digital logic circuits. That is, to improve evolvability, subcircuits are initially evolved. The architecture is applied as a prosthetic hand controller. By applying the proposed method, the best performance achieved is substantially better than that obtained by an artificial neural network.
