1 The function level evolvable hardware approach to synthesize the combinational multiple-valued and binary logic functions is proposed in rst time. The new representation of logic gate in extrinsic EHW allows us to describe behaviour of any multi-input multi-output logic function. The circuit is represented in the form of connections and functionalities of a rectangular array of building block...

When a system (natural or man-made) reaches a certain level of complexity, it becomes very difficult to grasp all of its underlying dynamics, and therefore, it becomes less controllable and less reliable [1]. However, the needs of the modern individual are fulfilled using extremely complex systems. What would our society be without computers, satellites, medicines, mega-software and free market...

An interesting approach of using genetic programming is to synthesize circuit with least possible number of logic gates and the same is presented in this paper. The genetic algorithm (GA) is one of the optimization techniques of evolutionary algorithm used to design evolvable hardware. This paper proposes the applicability of cluster based growth approach with genetic programming. Since in prev...

Evolvable hardware (EHW) has attracted increasing attention since the early 1990’s with the advent of easily reconfigurable hardware, such as field programmable gate arrays (FPGA’s). It promises to provide an entirely new approach to complex electronic circuit design and new adaptive hardware. EHW has been demonstrated to be able to perform a wide range of tasks from pattern recognition to adap...

Since 1992, year where Hugo de Garis has published the first paper on Evolvable Hardware (EHW), a period of intense creativity has followed. It has been actively researched, developed and applied to various problems. Different approaches have been proposed that created three main classifications: extrinsic, mixtrinsic and intrinsic EHW. Each of these solutions has a real interest. Nevertheless,...

Evolvable Hardware (EHW) has been proposed as a new technique to design complex systems. Often, complex systems turn out to be very difficult to evolve. The problem is that a general strategy is too difficult for the evolution process to discover directly. This paper proposes a new approach that performs incremental evolution in two directions: from complex system to sub-systems and from subsys...

Recently, hardware researchers have promptly begun to investigate alternative computational principles to the conventional ones. The main signs of these principles are inspiration in biology and their direct hardware implementation. Evolvable hardware, cellular computing or embryonic electronics are the most important examples. This paper describes different approaches to configuration, reconfi...

Recently there has been great interest in the design and study of evolvable systems in order to control the behavior of physically embedded systems. Due to the complexity of their architecture and their interaction with the environment, a Model-based Autonomous System approach was proposed by Williams to integrate a priori knowledge and reasoning methods of di erent kinds (Williams & Nayak 1996...

Evolvable Hardware (EHW) has been regarded as adaptive system acquired by wide application market. Consumer market of any good requires diversity to satisfy consumers’ preferences. Adaptation of EHW is a key technology that could provide individual approach to every particular user. This situation raises a question: how to set target for evolutionary algorithm? The existing techniques do not al...
