We propose a compact, high-speed, and highly testable parallel two-rail code checker, particularly suitable to implementing embedded checkers. In fact, it requires only two input codewords to satisfy the totally-self-checking or strongly code-disjoint property with respect to a wide set of realistic internal faults. Our checker can be employed to check the correct operation of a connected functional block using the two-rail code, to implement the output two-rail code checker of "normal… CONTINUE READING
