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