ABSTRACT:
A display control system which operates asynchronously with a microprocessor includes a display controller, display memory, character memory means, and a visual character attribute generator. By linking one or more row attribute bytes, or pointers, to each row of characters stored in the display memory the display controller performs character and row manipulation on a display device without transferring whole blocks of data in the display memory. Multi-region display segmentation into horizontal and vertical split regions, smooth or discrete scrolling of individual regions, and various editing functions are achieved by modifying the associated display memory pointers. In one embodiment the display controller is a single integrated circuit device.
