PURPOSE:To reduce an overhead at the time of switching a process, and also to make a system abound in flexibility at the time of its development and operation by executing an address conversion by selecting one of a relocation adding system and a mapping table system. CONSTITUTION:The titled system is provided with both a relocation register 2 and a mapping table 5, also selects one of a relocation adding system or a mapping table system by bits RL, MT of a program status word 6 in an operation control device, and converts a logical address 1 to a physical address 4. When developing a program, the address conversion is executed mainly by the mapping table system, and when the system is set, the address conversion is executed by the relocation adding system. |
