Abstract:
A graphic processing system comprising:a central processing unit; a graphic processor receiving commands and parameters from said central processing unit and generating display data using said received commands and parameters in accordance with predetermined processing procedures; and a memory storing said display data generated by said graphic processor, wherein said graphic processor has a first terminal for inputting a horizontal synchronizing signal from external of said graphic processing system and a second terminal for inputting a vertical synchronizing signal from external of said graphic processing system, said graphic processor fetches said horizontal synchronizing signal from external of said graphic processing system via said first terminal and fetches said vertical synchronizing signal from external of said graphic processing system via said second terminal, reads out said display data stored in the memory based on at least said fetched vertical synchronizing signal, when a display is set to a non-interlace mode, and reads out said display data stored in the memory based on at least said fetched vertical synchronizing signal of a predetermined timing, when the display is set to an interlace mode.
