Abstract

PURPOSE: To make it possible to perform the processing efficiently by executing the processing between areas segmented by a memory area mapping function in respect to a swapping function and a paging function.
CONSTITUTION: Swapping function 16 is provided which performs the roll-in/roll- out processing between contents of the second working set area on page memory 3 positioned in the CPU side and contents of working set area on page memory 3 positioned in the CPU side and contents of working set roll-out area 24 on external mass storage unit 21. Further, paging function 15 between contents in page unit of the first working set area on unit 3 as well as contents in page unit of the second working area and contents in page unit of the system program storage area on unit 21 as well as contents in page unit of the application program storage area is provided.
