<p>PURPOSE: To quickly update display by introducing output data obtained by a picture processor to a display controller in order to obtaining display or to a processor in order to obtain a secondary pixel image to a memory. CONSTITUTION: When a first display list stored in a main memory 12 is read and processed by the picture processor 20, pixel data is generated and transferred to the video display controller 22 by way of a routing circuit 26. In the controller 22, display is executed in CRT 24 through the use of the pixel data. When pixel data outputted from the processor 20 is transferred from the circuit 26 to a control processor 14, the control processor 14 generates the secondary pixel image of a form which is almost understood by the controller 22 in the main memory 12. Pixel data to be transmitted from the image in the main memory to the controller 22 by the processor 20 is generated at high speed at the time of updating display.</p> |
