Abstract

Check bit prediction is one of the schemes used to perform concurrent error detection in arithmetic and Logic functions. It has been considered for Parity codes, Bose's code, etc., and has been incorporated into some self checking processors. From literature survey to date, however, the only prediction method designed for Dong's code is for Arithmetic functions [12]. In this paper the mathematical equations for the check bit prediction of the Logical functions using Dong's code, are outlined and the check bit prediction hardware described.
