Multi-board run-time reconfigurable implementation of intrinsic evolvable hardware

Abstract

This paper is devoted to present a multi-board run-time reconfigurable (MRTR) system for evolvable hardware (EHW) and it is introduced with the aim to implement on hardware the bidirectional incremental evolution (BIE) method. The main features of this digital intrinsic EHW solution rely on the multi-board approach, the variable chromosome length management and the partial configuration of the reconfigurable circuit. These three features provide a high scalability to the solution. The design has been written in VHDL with the concern of not being platform dependant in order to keep a flexibility factor as high as possible. This solution helps tackling the problem of evolving complex task on digital configurable support. Furthermore some experiments are exposed and commented.
