System for performing rotation of pixel matrices

A system for rotating a source pixel matrix to provide a rotated destination matrix, the system on a computer system, the computer system including a processor and a temporary storage portion, the temporary storage portion including a plurality of rows, each row including a plurality of storage locations, the system comprising

• a non-volatile computer readable memory, the non-volatile computer readable memory including
• means for loading a first set of rows of the temporary storage portion with a lower portion of the source pixel matrix,
• means for loading a second set of rows of the temporary storage portion with an upper portion of the source pixel matrix,
• means for skewing the source pixel matrix loaded in first and second sets of rows to provide a skewed pixel matrix,
• means for alternately rotating selected portions of the skewed pixel matrix stored in selected rows of the first and second sets of rows horizontally and vertically to provide a rotated pixel matrix, and
• means for unscrambling the rotated pixel matrix to provide the rotated destination matrix.
