ABSTRACT:
An image processor which is connected to a system bus that connects a processor for forming graphic command related to image processing to a main memory that holds command and original image data, and draws image on the frame buffer based upon said graphic command from said processor, wherein said graphic processor has a data bus change-over unit which connects said system bus to a first data bus that is connected to a graphic data memory holding said graphic command and said original image data, or connects said first data bus to a frame buffer which holds the data to be displayed. The image processor realizes a high-speed processing at a reduced cost by using a graphic memory bus coupled to a graphic processor.
