Abstract
Abstract A graphic data processing apparatus is disclosed for accessing a memory which stores pixels having a number of bits which may be selected. Gaphic data is generated with one or more bits per pixel with a plurality of pixels of data being stored in one word of the memory. A physical address operation unit stores information of a current drawing point including a memory address of a word in the memory and a pixel address defining a position of a pixel in one word specified by the memory address. A data operation unit modifies a particular pixel having a number of bits which may be selected in the one word specified by the pixel address in accordance with a drawing instruction.
