Abstract
An improved bit shifter to provide data block shifting in a graphics processor. The shifter allows a multiple word, data block shifting to be achieved simultaneously and independently of other graphic functions. The shifter provides character block transfer for rotation of characters of a display. The shifter also provides bit block transfers for moving data from a source location to a destination location.
