A method of performing a bit block transfer (Bitblt) comprised of reading a pixel data sequence from a source trajectory, writing an X coordinate portion of the pixel data sequence to a destination trajectory, repeating the writing step to the end of a scan line in the event the X coordinate portion is smaller than the scan line, reset the X coordinate following the end of the scan line, reset a Y coordinate and write a successive X coordinate portion of the pixel data sequence to the destination register from an X coordinate start position when the Y coordinate actually advances in the pixel data sequence.
