Introduction

Abstract

This is a special issue of the Journal of VLSI Signal Processing comprising eight contributions invited for publication on the basis of novel work presented in a special session on “Parallel Processing on VLSI Arrays” at the International Symposium on Circuits and Systems (ISCAS) held in New Orleans in May 1990. Massive parallelism to cope with high-speed requirements stemming from real-time applications and the restrictions in architectural and circuit design, such as regularity and local connectedness, brought about by the VLSI technology are the key questions addressed in these eight papers. They can be grouped into three subsections elaborating on:

• Simulation of continuous physical systems, i.e., numerically solving partial differential equations.

• Neural architectures for image processing and pattern recognition.

• Systolic architectures for implementing regular and irregular algorithms in VLSI technology.
