摘要： A graphic processor which controls reading, writing and transfer of graphic data for a display memory that stores graphic data. The processor includes a first unit which stores first address information for addressing the display memory and first pixel address information which points a pixel position in a word specified by the first address information, a second unit which stores second address information for addressing the display memory and second pixel address information which points a pixel position in a word specified by the second address information, a third unit which shifts graphic data of multiple pixels included in two consecutive words to extract continuous 1-word graphic data, and a fourth unit which implements drawing computations pixel-wise concurrently for one word depending on the number of pixels included in a word. Even if transfer source graphic data lies across two consecutive words, the processor fetches the source data in single reading, processes the data word-wise at once, and stores the result in the display memory.
