Abstract
A CRT controller having a drawing function includes designation means to designate a predetermined area of an external memory as a reference area for tiling, and a drawing processor which transmits a display pattern in the reference area designated by the designation means, to a drawing area of the external memory. Since the CRT controller of this construction permits the use of the external memory easy of enlarging the capacity thereof for a tiling pattern, it realizes the tiling processing with a complicated tiling pattern.
