PROBLEM TO BE SOLVED: To realize an address conversion based on respective architectures in the case of sharing a main storage by plural processors having respectively different instruction architectures through a storage control. SOLUTION: Respective processors (a), (b) are provided with respectively different instruction architectures and each of main storages 210-213 is provided with a DAT processor, a DAT controlling storage and a software TLB. When a main storage access request is outputted from the processor (a) e.g. a TLBa is retrieved, and when there is no logical address, a DATa is started, an address conversion request with an IP number, a logical address and architecture ID is transferred to a DAT processor through a system control part SC. The DAT processor retrieves a software TLB corresponding to the conversion request, and when a logical address exists, registers a conversion result in the software TLB, registers the result also in the TLBa and stops the operation of the DATa. When no logical address exists a corresponding DAT program stored in the DAT control storage is started and a conversion result is registered in the software TLB.
