  13   The Dewarp Engine provides high-performance dewarp processing for the
  14   correction of the distortion that is introduced in images produced by fisheye
  15   and wide angle lenses. It is implemented with a line/tile-cache based
  16   architecture. With configurable address mapping look up tables and per tile
  17   processing, it successfully generates a corrected output image.
  18   The engine can be used to perform scaling, cropping and pixel format
  19   conversion.
