<p>PROBLEM TO BE SOLVED: To reduce hardware quantity by providing in common a table for translating an address on access to a memory from a logic address to a physical address for a processor in an own-device and a processor outside the own-device in common. SOLUTION: An address translation device 220 is constituted of a selection device 221 and a translation table device 222. In the selection device 221, an arithmetic processor main storage access path 201 and a remote access controller main storage access path 211 are set to be inputs and it alternatively outputs a main storage access request from the arithmetic processor 200 and a remote access controller 210. The corresponding relation of the logic address and the physical address is mentioned in the translation table of the conversion table device 222. Thus, the table for translating the address on access to the memory from the logic address to the physical address is provided in common to the arithmetic processor 200 in the own-device and the processor outside the own- device.</p> |
