PROBLEM TO BE SOLVED: To provide an efficient information processing technology including an image processing arithmetic operation corresponding to a multi-task. SOLUTION: The management processor of a main processor transmits a task switching request signal including information related with a switched task to the image processing side communication part of a graphic processor by a control side communication part in a step S2. The memory control part of the graphic processor reads image relevant data related with the task from a graphic memory in a step S4, and makes the image relevant data retreat to a main memory in a step S6. Data related with the switched task are read from the image relevant data previously saved to the main memory in a step S8, and return to the graphic memory in a step S10. An acceptance permission signal indicating that the preparation of task switching is arranged is transmitted from the image processing side communication part to the control side communication part in a step S12. The main processor confirms the acceptance permission signal, and performs the task switching of the management processor. COPYRIGHT: (C)2006,JPO&NCIPI |
