The paper introduces a new method for the design of realworld applications of evolvable hardware using common FPGAs (Field Programmable Gate Arrays). In order to avoid “reconfiguration problems” of current FPGAs a new virtual reconfigurable circuit, whose granularity and configuration schema exactly fit to requirements of a given application, is designed on the top of an ordinary FPGA. As an ex...

1. 서론 본 논문에서는 유전자 프로그래밍에 기반하여 개발된 온 라인 적응 학습 가능한 진화 하드웨어를 위한 진화 학습 방법에 관하여 소개하고자 한다. 진화 하드웨어는 환경 변 화나 임무변경에 맞추어 스스로의 회로를 실행시간 중에 변경할 수 있는 새로운 개념의 하드웨어이다 [1]. 진화 하 드웨어는 유전 알고리즘(Genetic Algorithms)이나 유전자 프 로그래밍(Genetic Programming)과 같은 진화 알고리즘을 이 용하여 동적 재구성을 실시하게 된다. 진화 하드웨어의 진 화 방법으로는 유전자 프로그래밍이 선택되었다. 유전자 프로그래밍은 자연선택과 유전 연산자를 이용하여 가장 적 합한 프로그램을 찾아가는 진화연산의 한 방법이다 [2]. 트리 구조를 이용한 유전자 프로그래밍의 개체 구조...

This paper presents a novel method for predictive lossless image compression via evolving a set of switches, which can be implemented easily by intrinsic evolvable hardware mode. A set of compounded mutations for binary chromosome through combining the local asexually reproducing with multiple mean step size search was proposed, and a gradually approach method for evolving larger scale images w...

The requirements of a general purpose massively parallel processing system are outlined. The suitability of a finegrained self-reconfigurable system to general massively parallel processing is shown. A new type of selfreconfigurable device called the PIG is introduced, and details of its design and operation are explained. The PIG’s uniqueness compared to other reconfigurable systems is discuss...

Bidirectional incremental evolution (BIE) has been proposed as a technique to overcome the ”stalling” effect in evolvable hardware applications. However preliminary results show perceptible dependence of performance of BIE and quality of evaluated circuit on assembling strategy applied during reverse stage of incremental evolution. The purpose of this paper is to develop assembling strategy tha...

Robust electronics is a challenge that the evolvable hardware field is addressing. This paper focusses on tolerance of faults where faults may arise through defects in the technology or unforeseen events. By relaxing the digital abstraction we enable evolution to find robust circuit architectures, exploiting non digital signal variations where necessary. Using a flexible technology and environm...

This paper describes a data compression system using Evolvable Hardware (EHW) for digital color electrophotographic (EP) printers. EP printing is an important technology within digital printing, which is currently having a significant impact on the printing and publishing industry. Although, it requires data-compression to reduce the cost for transferring and storing large EP images, traditiona...

Evolutionary algorithms have been gaining increased attention the past few years because of their versatility and are being successfully applied in several diierent elds of study. We group under this heading a family of new computing techniques rooted in biological evolution that can be used for solving hard problems. In this chapter we present a survey of genetic algorithms and genetic program...

Evolvable Hardware (EHW) is a new concept that aims the application of evolutionary algorithms to hardware design. EHW can adapt itself to unknown environment based on features of the reconfigurable hardware. This paper presents outlines of the idea of using some EHW agents in a distributed system. These agents need to set up a self-organized communication to achieve the predesigned goal. The e...
