Abstract
When a central processing unit requests a program, the central processing unit loads a program from an external storage device onto a physical page. The physical address of the physical page where this program is stored is associated with a logical address in a program cache space. Information about addresses in this program is translated in this program cache space. Then, the physical address of the physical page where the program is loaded is associated with a logical address in a process space. Therefore, the central processing unit can thereafter access the program in the process space without copying a physical page for address alteration. When the central processing unit executes writing on the program in the process space later, the physical page is copied.
