Abstract

This paper presents a new method for fault-tolerant computing where for a given error rate, r, the hamming distance between correct inputs and faulty inputs, as well as the hamming distance between correct results and faulty results, is preserved throughout processing; thereby enabling correction of up to r transient faults per computation cycle. The new method is compared and contrasted with current protection methods and its cost/performance is analyzed.
