PURPOSE:To perform an optimum memory management for every program by assigning a real storage capacity in every program processing unit and performing page conversion in accordance with a page conversion system designated with the program. CONSTITUTION:An address part of a virtual file 12 which exists on a main memory 16 is retrieved in accordance with operation of the program by a TLB 17. Nevertheless, if a program which is not stored on the memory 16 is required, a storage management control part 14 refers to a task management table TCB 16-2 to operate a CPU13 in accordance with an optimum page conversion system of the program, for example, a program of the FIFO system in a storage management program storage part 15. Thus, the CPU13 converts plural pages stored in the beginning of this program to plural desired pages by a list 16-3, and hereafter, the program of converted pages is used to continue a job. In this manner, the program is controlled most suitably. |
