  • Patent number: 7894094
    Abstract: A system and method to provide 180-degree rotation of image data at full throughput. The system includes a memory access controller that writes bursts of image data into a rotation buffer. The image data is then read out of the rotation buffer in the reverse order from which it was written to thereby accomplish rotation. By alternating the position in the rotation buffer in which the image data is written such that an image is either written into the buffer from top and read from the bottom or written into the buffer from the bottom and read out from the top, a one page rotation buffer of can be used to concurrently process two pages.
