Abstract
An apparatus for rotating bit-mapped data includes a specially designed data array (9) that includes a normal port (10) for accessing horizontal words of data and a rotated port (15) for accessing vertical words of data. In addition, address generating logic (6) is provided that automatically generates proper address seqences for accessing the normal words or the vertical words as appropriate during a rotation operation. The apparatus is cascadable (FIG. 29) to provide effectively any size data array.
