An Overview

Abstract

The area of fault-tolerant computing has become increasingly important with the growth in complexity of computer hardware and software. Hardware issues range from the design and analysis of fault-tolerant circuits to large fault-tolerant computing systems. Software issues range from the design and analysis of fault-tolerant data structures to large fault-tolerant software systems. While many problems are being actively studied in both the hardware and software domains, efforts at designing fault-tolerant VLSI and WSI systems have been of particular interest in the last decade. This is due to both the very large number of components in such designs, and thus the high likelihood of faults, as well as to the regular structure of many of these architectures, which makes them particularly well-suited for fault-tolerant design.
