<P>PROBLEM TO BE SOLVED: To reduce access frequency to an external memory. <P>SOLUTION: A command processing part 101 retrieves object data stored in a command memory 200 by an amount capable of being stored in a command buffer 102. A command buffer control part 103 stores the retrieved object data in the command buffer 102. The command buffer control part 103 retrieves the object data stored in the command buffer 102, and a drawing processing part 105 performs drawing processing for each division image area of the object data divided by a tile division part 104 and outputs the image data to which drawing processing was performed to an image memory 300. After the drawing processing of the object data, the command buffer control part 103 deletes the object data from the command buffer 102. Then, the command processing part 101 retrieves object data which is stored in the command memory 200 and has not been retrieved, and the process is repeated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
