Abstract :
This paper examines a conventional method for optimizing the design of CSD multipliers based on parallel Signed-Weight (SW) counter-tree architecture and another novel evolutionary-computation approach to automatically seeking optimal designs of multipliers. The comparisons of experimental results between them indicate that the evolutionary-computation method in most cases is comparable to or outperforms the conventional designs using CSD number representation
