[0022] figure 1 It is a block diagram showing the configuration of the information processing device 1000 according to the first embodiment of the present invention. The information processing device 1000 includes a graphics processor 100 , a main processor 200 and a main memory 50 . The information processing device 1000 is connected to the display device 500 , and outputs images and videos obtained as a result of processing by the main processor 200 and the graphics processor 100 . exist figure 1 Among them, each element described as a functional block that performs various processes can be configured by a CPU, a memory, or other LSI in terms of hardware. program to achieve. Therefore, those skilled in the art should understand that these functional blocks can be realized by only hardware, only software or their combination, and are not limited to one of them.
[0023] In this information processing device 1000 , an operating system (hereinafter abbreviated as OS) that p...

[0056] In the first embodiment, when the management processor 32 of the main processor 200 performs task switching, the image 3 In Step S2, the control-side task switching unit 64 sends a task switching request signal to the image processing-side task switching unit 74, but in this embodiment, instead of this step, a shared address steps. The structure of the information processing device 1000 and figure 1 and figure 2 same. The description here is the same as that in the first embodiment figure 2 function and image 3 different steps.
[0057] Figure 5 It is a block diagram showing the structure of the management processor 32 provided in the main processor 200, the control block 20 provided in the graphics processor 100, and the shared register 80 accessible to all of them in this embodiment. In addition to the first embodiment, the control-side task switching unit 64 of the management processor 32 also has a function of writing to the shared register 80 . Further...

[0062] In the first embodiment, the transfer of the drawing data from the main processor 200 to the graphics processor 100 is through each sub-processor 30 that processes the task that needs to perform the image processing and transfers the data to the main memory 50. Data is managed by the management processor 32.
[0063] In this embodiment, as shown in FIG. 6 , one sub-processor 30 controls the transfer of rendering data for image processing that occurs during the processing of tasks by the sub-processor 30 . In the figure, this sub-processor 30 is particularly referred to as a control processor, and in order to distinguish it from other sub-processors 30 , it is given a different reference numeral 31 . The drawing data to be transferred to the graphics processor 100 is temporarily transferred from the sub-processor 30 to the transfer control processor 31 (for example, arrow 86 ), and is appropriately transferred and processed by the transfer control processor 31 (for examp...
