PURPOSE:To attain efficient logout control by deciding a logical address to each register or the like and making a service processor control logout by the logical address so as to ensure the continuity of the logical address. CONSTITUTION:The logical address is set to a logical address register 3b by a service processor 1 via an interface 2a or the like of a CPU2. When this logical address is inputted to an address converting memory 3c, a physical address corresponding to it is outputted and stored in a register 3k. A selector 3d selects one of registers 3e-3g designated by the address stored in the register 3k, transfers the content to an interface 3a, from which its content is transferred to the device 1. The device 1 knows of the content of the register designated by the logical address and the logout control is attained efficiently. |
