<p>PURPOSE:To shorten the paging processing time and at the same time to reduce the capacity f an auxiliary storage by outputting the compressed page contents to the auxiliary storage when a page-out operation is carried out. CONSTITUTION:A compression information setting part 4 receives a report of a page-out subject page and reads the information on the page out of a main storage 1. Then the part 4 compresses the information and searches for an unused part of an auxiliary storage 2 by reference to an auxiliary storage control part 6 to output the compressed information. When a page fault interruption occurs, a memory restoring part 5 refers to a page table 7 to serach for the storing position of the storage 2 for the page having a page fault. Then the part 5 reads out the stored compressed information and restores this information to output it to an idle page frame of the storage 1. Thus it is possible to reduce the quantity of input/output data to the storage 2 having a low processing speed compared with the internal processing speed of an electronic computer system. Then the paging processing time is shortened and at the same time the capacity of the storage 2 is reduced.</p> |
