PURPOSE:To avoid the response delay of other programe by causing a program inself to supply a shunt area, where the program is shunted, when the program having a priority level higher than other programs is executed in non-resident programs which use a wide non-resident area. CONSTITUTION:Non-resident programs n1 and n2 which are stored in auxiliary memory 2 at a normal time and are transferred from memory 2 to main memory 1 at an emergency time to execute the processing are equipped, and non-resident area NK is provided in memory 1, and area 200 where programs are shunted is provided in memory 2. Then, when program n1 was loaded into area NK of memory 1 and is executing the processing and high-priority level porgram n2 is started. program n1 is shunted. At this time, if program n1 uses large non-resident area NK and requires a high response efficiency, area 201 where the program itself is shunted is provided in memory 2 previously, and program n1 is shunted in area 201 when program n1 is transferred to memory 1. |
