Abstract
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.
