PROBLEM TO BE SOLVED: To provide an efficient information processing technology including an image processing arithmetic operation corresponding to a multi-task. SOLUTION: A plurality of sub-processors 30a and a management processor 32 process the same tasks A, and a graphic processor 100 performs image processing A' corresponding to the same task A as the management processor 32. When a certain sub-processor 30b processes a task B different from the task A, the image processing A' related with the task A generated in the sub-processor 30a is accepted by the graphic processor 100, and plotting data (a) are transferred to the graphic processor 100 (arrow 80). On the other hand, when the necessity of the execution of image processing B' related with the task B is generated in the sub-processor 30b, plotting data b of the image processing B' are made to retreat to a main memory 50 by the sub-processor 30 (arrow 82). Afterwards, when the image processing B' corresponding to the task B is started by the graphic processor 100, the plotting data b are transferred from the main memory 50 to the graphic memory 10 (arrow 84).
