Abstract: There is provided a graphics processing system that includes a main processing unit and a graphics processing unit (GPU). The main processing unit puts rendering commands generated using a graphics library in the queue of a command buffer in a main memory. In this process, the library function offered by the graphics library is converted into the rendering commands, without any rendering attributes retained in the library. The GPU reads and executes the rendering commands stacked in the command buffer, and generates rendering data in a frame buffer.

Abstract: A plurality of sub-processors and a management processor process the first task. A graphic processor unit executes image processing corresponding to the first task processed by the management processor. One of the sub-processors 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 and associated first rendering data is transferred to the graphic processor unit. Meanwhile, when the need arises in the one of the sub-processors for a second image process related to the second task, the one of the sub-processor saves second rendering data for the second image process in a main memory. Subsequently, when the graphic processor unit starts the second image process corresponding to the second task, the second rendering data is transferred from the main memory to a graphic memory.

Abstract: A graphic memory is space-divided into a first area and a second area. In the first area, a task corresponding to a predetermined application is executed regardless of which task is processed by a main processor. A switchable area is divided in time so that data related to tasks corresponding to a plurality of applications is sequentially stored in the switchable area in accordance with task switching in the main processor.

Abstract: A management processor of a main processor unit transmits a request for task switching that includes information related to a task performed after the switching, from a main processor communication unit to a graphic processor communication unit of a graphic processor unit. A memory controller of the graphic processor unit reads image-related data related to a task before the change from a graphic memory and saves the read data in a main memory. The memory controller reads the data related to the task after the change from the main memory, which stores previously saved image-related data. The memory controller restores the read data to the graphic memory. The graphic processor communication unit transmits an acceptance permit signal indicating that the graphic processor unit is ready for task switching to the main processor communication unit. After acknowledging the acceptance permit signal, the main processor unit switches between tasks in the management processor.
