    摘要: One of processors connected effectively to a system is allocated to a master processor and the other remaining processors are allocated to slave processors. Each processor compares the self processor number of a processor number register and the processor number of the other processor of a processor effective register. For example, when the self processor number is smallest as compared with the other processor numbers, it is recognized that the self processor is a master processor. A master initialization diagnosing process after completion of the allocation is monitored by the slave processor. When an abnormality of the master processor is recognized, a degeneration to disconnect the master processor from the system is executed and is again reconstructed by the allocating process of master/slaves. Even when an abnormality occurs in the master processor, the operation in which the system was degenerated can be executed until the minimum construction in which two or more processors normally operate.

    摘要: A device for the initial-diagnosing of processors is provided with a processor module, a storage unit, an address allocation unit and a diagnostic execution unit. The processor module has a processor and a cache storage unit. The storage unit stores an initial diagnostic setting program which diagnoses the processor and the cache storage unit. The address allocation unit allocates the addresses of the processor by making the addresses of the processor correspond to the addresses of the cache storage unit so that the cache storage unit is accessed by the processor. The diagnostic execution unit reads the initial diagnostic setting program stored in the storage unit into the addresses of the cache storage unit allocated by the address allocation unit, and executes the initial diagnostic setting program.
