PURPOSE:To improve a drawing speed by using an image dual port memory as a segment memory and rapidly and serially accessing the memory. CONSTITUTION:The image dual port memory is used as the segment memory 21. When the memory 21 is rapidly and serially accessed through a CPU 3, serial data from the memory 21 are directly supplied to an accelerator 15 and the serial data are rapidly and serially transferred through a CRT controller 16. Consequently, the drawing speed can be improved. |
