Abstract

PURPOSE: To detect the faults of plural processors via a single fault monitor timer device by securing such constitution where an interruption produced from the fault monitor timer device owing to the fault of a certain processor is accepted and the faulty processor is discriminated through a memory area for a processor transmitting a health signal.
CONSTITUTION: At the output time point of a health signal, a health signal output selection means 60 selects the processors 1WN which transmit the system time points obtained from a system time area and the health signals received from a health signal output processor memory area 50. In case an interruption is received from a fault monitor timer device 10 when either one of the processors 1WN produces the abnormality, a faulty processor discriminating means 90 detects the faulty processor. Thus a single device 10 can detect the faults of plural processors 1WN.
