Abstract

PURPOSE: To prevent the processing speed of CPU from decreasing by loading data from a secondary memory unit within the minimum range when a fault occurs in read access.
CONSTITUTION: The memory contents of external mass memory unit 3 are transferred to and held in main memory unit 2 in CPU1, page by page, and if a page fault signal is generated in processing, pooling processing part 9 is actuated by AND processing 8 to store queue memory 4 with address information, causing the page fault, and write data in pairs. In this pooling, read access is attained and if the page fault occurs, processing part 10 reads pool data out of memory 4 and, at the point in time when a fixed gape unit is loaded into unit 2, sends the writing indication of the pool data to unit 2.
