<P>PROBLEM TO BE SOLVED: To provide a monitoring system and monitoring method of a multi-CPU system for discriminating the classification of a failure. <P>SOLUTION: A monitoring system 1 of a multi-CPU system having a plurality of CPU terminals (CPU1, CPU2, through CPUn+1) connected via a serial bus 2 includes a bus 3 for failure discrimination connected to the plurality of CPU terminals (CPU1, CPU2, through CPUn+1). When any response signal to a first response request signal transmitted from one CPU terminal (CPU1) via the serial bus 2 to the other CPU terminal (CPU2) is not received, a second response request signal is transmitted from one CPU terminal (CPU1) via the bus 3 for failure discrimination to the other CPU terminal (CPU2), and the classification of the failure of the other CPU terminal (CPU2) is discriminated on the basis of the presence/absence of the reception of a response signal to the second response request signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
