Evolvable hardware: pumping life into dead silicon

چکیده
The design productivity gap in the electronic industry is a well-known fact. How can the design community utilize the design capacity that technology is offering and at the same time ensure its correctness? To find solutions to the problem of developing large and complex designs new design paradigms are required (Semiconductor Industry Association, 1997). One possible solution is to turn away from traditional design techniques following the various design and testing phases and instead allow hardware to evolve until a correct solution is found. This technique is termed hardware evolution or equally, evolvable hardware. Evolvable hardware may be considered to be a subset of evolutionary computation, where the evolved solution is represented in hardware instead of software. In this chapter the field of evolvable hardware is introduced along with some of the limitations which prevent evolution of complex circuits. The process of natural development is analysed with respect to the features which may be represented in a developmental process for circuit development. The technology itself is also studied to identify features which development may exploit. We present some initial experiments for circuit development based on Lsystems, a mathematical formalism for development (Lindenmayer, 1968). The results of these experiments along with our analysis of development and our technology lead us to describe some of the challenges we face in our bid to develop electronic circuits.

On Feasibility of Adaptive Level Hardware Evolution for Emergent Fault Tolerant Communication
A permanent physical fault in communication lines usually leads to a failure. The feasibility of evolution of a self organized communication is studied in this paper to defeat this problem. In this case a communication protocol may emerge between blocks and also can adapt itself to environmental changes like physical faults and defects. In spite of faults, blocks may continue to function since ...
