Diversity techniques for concurrent error detection

Abstract

Concurrent error detection (CED) techniques are widely used to ensure data integrity in digital systems. Data integrity guarantees that the system outputs are either correct or an error is indicated when incorrect outputs are produced. This dissertation presents the results of theoretical and simulation studies of various CED techniques. The CED schemes studied are based on diverse duplication, simple duplication of identical implementations, and error-detection techniques like parity checking. The study aimed at [1] a quantitative comparison of the effectiveness different CED schemes, and (2) developing design techniques for efficient concurrent error detection.
