GRAPHICS PROCESSING APPARATUS

PROBLEM TO BE SOLVED: To solve a problem wherein, when a system configuration where the CPU is related to graphics processing is used, the performance of the whole system is reduced by the CPU as a bottleneck. SOLUTION: A main processing unit 100 has a main processor 102 for executing general-purpose processing, and a sub-processor 104 for executing operation related to the graphics. The sub-processor 104, instead of main processor 102, generates a rendering command based on an application program, stacks it in a command buffer 10 of the main memory 120, generates geometry data 12 and texture 14 required for executing the generated rendering command, and holds them in the main memory 120. A graphics processing unit 200 reads the rendering commands held in the command buffer 10, and executes the rendering processing. COPYRIGHT: (C)2008,JPO&INPIT
