PURPOSE:To accelerate drawing processing speed when parallelly executing the drawing of a two-dimensional graphic and the drawing of a three- dimensional graphic. CONSTITUTION:When the drawing of the two-dimensional graphic is executed to a frame buffer 5 by a drawing processing part 4 based on commands and data outputted from a processor 1, the commands and data from a GA 2 are selected through a FIFO memory 2b for output by a command selection part 3 corresponding to the halt time of the drawing processing part 4, and the drawing of the three-dimensional graphic is executed to the frame buffer 5 by the drawing processing part 4. |
