ABSTRACT:
A fault tolerant circuit having improved error correction and detection properties takes advantage of two distinct forms of information redundancy: modular redundancy and parity check bit redundancy, in a cooperative fashion. In particular, it is shown that simple majority voting logic circuits, when employed in the subject environment, provide an easily realized mechanism for error correction and error detection. This results in an extremely fault tolerant information system.
