ABSTRACT:
A virtual storage managing system in which the storage address is managed by means of a virtual address, and the virtual storage area which can be assigned by the virtual address is divided into an address non-translation area which does not require the address translation and an address translation system which requires an address translation. The address translation area is divided into an address fixed area and an address variable area. In the address translation area, the correspondence between the virtual address and the real address is fixed in a 1:1 fashion, whereas, in the address variable area, the correspondence is determined at the time of starting of execution of a program and is dismissed when the execution of the program is completed.
