Abstract

PURPOSE: To reduce the overhead to support the virtual memory function, by providing the means designating the access enable area on the main memory unit and performing the address conversion automatically when CPU or channel accesses the main memory.
CONSTITUTION: The absolute address of the head and final addresses of region is stored in the register AMR and it is used when accessing is made from the channel to the main memory unit. Further, to the VMM program area of the program region of virtual computer monitor VMM, and managing program to operate a plurality of operating systems at the same time is stored, and the prefix area is used to give the interruption information and control taken place at the execution of program to the VMM interruption processing program for interruption processing. Further, to the VM program area of the VM program region the program given by the user is stored and the VM prefix area is used to give the result of interruption processing by the VMM program to the VM program.
