Abstract
A graphic processing system for text display which includes a data processing unit, composed of a memory and a processing unit, for creating character code information, and a graphic data processing unit, composed of a graphic data processor and a frame buffer, for creating pixel information. The text display is performed by creating character code information in the data processing unit, supplying the character code information from the data processing unit to the graphic data processor, creating addresses on the frame buffer corresponding to the character code information by the graphic data processor, reading out a character font from a second area of the frame buffer using the created addresses, writing the read-out character font in a predetermined position of a first area of the frame buffer, and outputting the display data at the first area of the frame buffer to a display unit.
