Checkbit Prediction for Logic Functions By Using Dongs Code Method

Detecting errors in arithmetic and logic operations is very important, and the simplest way is by using Duplication. However, the use of duplication is very expensive. In this arithmetic and logic function the errors are detected by using check bit prediction schemes. The only available technique that can be used to detect the three types of errors (transfer errors, arithmetic errors [12], and logic errors) where only one non-arithmetic code for example Parity code, Berger code, Dong's code. In this paper the mathematical equations for the check bit prediction of the logical functions using Dong's code are outlined.
