Systems, methods and devices for rotating image tiles using line segment read buffers
Abstract:
An embodiment generally relates to a device for rotating image tiles using line segment read buffers. The device comprises an image memory configured to store an image and a plurality of buffers, wherein the image comprises a plurality of tiles. The plurality of buffers comprises line segment read 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 macro-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.
