<P>PROBLEM TO BE SOLVED: To provide systems, methods and devices for rotating image tiles using line segment read buffers, which can rotate images without the use of intermediate memory or auxiliary memory. <P>SOLUTION: The device comprises an image memory to store an image, and a plurality of buffers. The image comprises a plurality of tiles. The plurality of buffers comprises line segment buffers configured to interface with the image memory to read line segments of the plurality of tiles from the image memory. A rotator logic module is configured to micro-rotate the line segments, aggregate the line segments as rotated tiles, and micro-rotate the rotated tiles to determine an address of the image memory at which to write the rotated tiles. Write buffers are configured to write the rotated tiles to the image memory at the determined address. <P>COPYRIGHT: (C)2012,JPO&INPIT |
