Abstract

In this paper we have presented a method to detect errors in cellular arrays. Space limitation of cellular processors forced us to look at the approaches whose overhead is as little as possible. Therefore, we have shown some simple examples for self-checking processing elements where we managed to get reasonable results in additional space and time. Cellular programs using self-checking PEs as building blocks ensure higher reliability of cellprocessors. We hope that this concept will lead to new results in cost-effective fault-tolerance procedures for various applications.
