Abstract
PURPOSE:To freely produce a virtual space regardless of the arrangement of a physical memory by saving once and MMU (memory control unit) control program into another virtual address. CONSTITUTION:A conversion table is produced for a virtual space 2 where an MMU control program 4 is mapped over both MMU control programs 5 and 6. Then a physical memory space 1 is switched to the space 2. A jump is given to a virtual address of an MMU control program 6 and an MMU control program 7 is mapped. Then a jump is given to a virtual address of the program 7. A conversion table is produced for an original virtual space 3 for switch to this space 3. Thus the virtual address receives no influence from the arrangement of a physical memory and a free virtual space can be obtained.
