COMPUTER DEVICE FOR PARALLEL PROCESSING

PURPOSE:To detect the generation of an accident precisely by taking out output signals from corresponding circuits respectively during no calculation period of computers, differentiating these signals, uniforming their polarity and then discriminating coincidence or inconsistency between these signals and an inverted clock pulse. CONSTITUTION:Output signals are taken out from main circuits ak, bk constituting the computers in A and B systems respectively during no calculation period. These output signals are differentiated by differential circuits 21, 22, their polarity is uniformed by polarity coincidence circuits 23, 24 and the outputs of the circuits 23, 24 are inputted to AND circuits 25, 26. Clock pulses CL are supplied to the inverted input terminals of the AND circuits 25, 26, so that the coincidence or inconsistency of both inputs is discriminated and the generation of an accident of the circuit in each system.
