MULTIPROCESSOR SYSTEM

PROBLEM TO BE SOLVED: To highly efficiently operate a network in a multiprocessor system of a network constitution. SOLUTION: The multiprocessor system comprises: a processor bus on an input side for supplying input data; a first processor group connected to the processor bus on the input side; a second processor group connected with the first processor group through the network to which data processed by the first processor group are transferred; a processor bus on an output side connected to the second processor group for outputting processing data processed by the second processor group; and registers on the input side and on the output side connected to the processor buses on the input side and on the output side, respectively, for recording the abnormality information of the processor group connected to the corresponding processor bus. When an abnormality occurs in the first or second processor group, the abnormality information of the register in which the abnormality information of the processor group is recorded is reported to the other register.
