Abstract

PURPOSE:To perform IC-implementation efficiently by facilitating a doubled comparison check by applying a common input to two integrated logic circuits having exactly the same functions and by outputting an error signal from an OR gate by detecting their outputs. CONSTITUTION:Integrated logic circuits 1 and 1', having exactly the same functions, are applied with common input signal 2 to put the same functions in operation simultaneously. Outputs of internal logic circuits of circuits 1 and 1' are sent to output circuits 5 and 6, and 5' and 6'; outputs B of those output circuits are sent to terminals 3a...3n, and 3a'...3n', and outputs C to OR gates 7 and 7'. Outputs of those gates 7 and 7' are inputted to OR gate 9 via error detecting circuits 8 and 8' of circuits 1 and 1' and from gate 9, error signal 10 is outputted. Consequently, a doubled comparison check is made nearly without increasing hardware and electric power consumption, and the integration is done efficiently.
