A plurality of sub-processors (30) and a management processor (32) process the first task. A graphic processor unit (100) executes image processing corresponding to the first task processed by the management processor (32). One of the sub-processors (30) performs a second task different from the first task. An image process related to the first task and originated in the sub-processor is accepted by the graphic processor unit (100) and associated first rendering data is transferred to the graphic processor unit (100). Meanwhile, when the need arises in the one of the sub-processors (30) for a second image process related to the second task, the one of the sub-processor (30) saves second rendering data for the second image process in a main memory (50). Subsequently, when the graphic processor unit (100) starts the second image process corresponding to the second task, the second rendering data is transferred from the main memory (50) to a graphic memory (10). |
