The paper deals with a new approach to the design of adaptive hardware using common Field Programmable Gate Arrays (FPGA). The ultimate aim is to develop evolvable IP (Intellectual Property) cores. The cores should be reused in the same way as ordinary IP cores are reused. In contrast to the conventional cores, the evolvable cores are able to perform autonomous evolution of their internal circu...

This paper proposes an evolvable hardware system with capability of evolution under uneven image environment, which is implemented on reconfigurable field programmable gate array (FPGA) platform with ARM core and genetic algorithm processor (GAP). Parallel genetic algorithm based reconfigurable architecture system evolves image filter blocks to explore optimal configuration of filter combinatio...

A multi-board run-time reconfigurable (MRTR) system for evolvable hardware (EHW) 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 feat...

Evolvable hardware provides the capability to evolve analog circuits to produce amplifier and filter functions. Conventional analog controller designs employ these same functions. Analog controllers for the control of the shaft speed of a DC motor are evolved on an evolvable hardware plaform utilizing a Field Programmable Transistor Array (FPTA). The performance of these evolved controllers is ...

Adaptively evolvable systems require some reconfigurable capabilities, habituated within the FPGA. FPGA’s can be integrated with either Dynamic Partial Reconfiguration (DPR) or Virtual Reconfiguration Circuits (VRC). Since DPR allows lesser resource utilization on the FPGA available logic, which has a positive repercussion in power consumption compared to VRC’s, we are using FPGA’s with native ...

Evolvable hardware is a type classification of reconfigurable hardware. This gives designer run time hardware configuration facility that is optimized in many senses. The basic methodology of designing evolvable hardware comes from genetic algorithm. Genetic algorithm defines different operator on a given problem that are run iteratively to reach optimal solution. One such operator is crossover...

This paper focuses on characteristics and applications of evolvable hardware (EHW) to space systems, and describes research directions and ongoing work at JPL. Our motivation for looking at EHW is the need for more autonomous adaptive space systems. Even with a best design, incoqmrating the most advanced flight qualified technology at the time, and considering what is known about the environmen...

Recently there has been great interest in the idea that evolvable systems based on the principles of Arti cial Life can be used to continuously and autonomously adapt the behavior of physically embedded systems such as mobile robots, plants and intelligent home devices. At the same time, we have seen the introduction of evolvable hardware(EHW): new integrated circuits that are able to adapt the...
