DATA PROCESSOR

A data processor that includes a central processing unit, a graphic controller, a display controller, an image recognizing module, a memory controller and image data input units is disclosed. The components can be formed on a single semiconductor substrate. The display controller can perform display control on image data. The image data input unit stores the image data into a first area in the external memory. The image recognizing module or central processing unit executes an image process on the image data in the first area or image data in a second area, and stores a result of the process in a third area of the external memory.
