The new Virtex device is for many people the solution to the long term problem of implementing random configurations on Digital Electronic devices as is required in the paradigm of Evolvable Hardware. It has previously been shown that Evolvable Hardware was possible on these devices and that it can be accomplished using partial reconfiguration to speed up the configuration process. Unfortunatel...

Traditional approaches to evolvable hardware (EHW), using a direct encoding, have not scaled well with increases in problem complexity. To overcome this there have been moves towards encoding a growth process, which however have not shown a great deal of success to date. In this paper we present the design of a morphogenetic EHW model that has taken the salient features of biological processes ...

Evolvable Hardware (EHW) has been proposed as a new method for evolving circuits automatically. One of the problems appearing is that only circuits of limited size are evolvable. In this paper it is shown that by applying an approach where the training set as well as each training vector is partitioned, large combinational circuits can be evolved. By applying the proposed scheme, it is shown th...

An original approach to automatic design of image operators is presented in this paper. The proposed solution employs evolvable hardware at simplified functional level and produces image operators (digital circuits), which can compete against traditional designs in terms of quality and implementation cost in Xilinx’s chips.

Evolvable Hardware (EHW) refers to HW design and self-reconfiguration using evolutionary/genetic mechanisms. The paper presents an overview of some key concepts of EHW, describing also a set of selected applications. A fine-grained Field Programmable Transistor Array (FPTA) architecture for reconfigurable hardware is presented as an example of an initial effort toward evolution-oriented devices...

Evolvable hardware (EHW) refers to self-reconfiguration hardware design, where the configuration is under the control of an evolution algorithm. One of the main difficulties in using EHW to solve real-world problems is scalability, which limits the size of the circuit that may be evolved. This paper outlines evolvable hardware based on a 2-LUT (2-input lookup table) array, which allows the evol...

The concept of Evolvable Hardware has attracted increased attention because it offers adaptive and highly optimized systems. Also there have been some researches toward implementing reconfigurable network devices that can change their architecture while running as a network node. In combination with evolvable hardware concept we can build adaptive and self-optimizing network systems which can a...

In this paper we have surveyed recent approaches for design of approximate circuits using Evolvable Hardware. We have discussed some challenges faced during evolution of digital circuits. Then we have proposed spatially varying mutation and cross over rates as possible remedy and discussed its superiority on uniform mutation and crossover rate for digital circuits. Keywords—Evolvable hardware, ...

Turning away from traditional design techniques, which follow the various phases of design and testing, Evolvable Hardware circuits are created through evolutionary strategies aimed at improving the circuits behavior with respect to a given specification. These evolutionary strategies are stochastic search methods that mimic the process of natural biological evolution and are implemented as Evo...
