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.

Abstract: An embodiment generally relates a device for rotating images. The device includes an image memory configured to store an image and a plurality of buffers. The plurality of buffers are configured to interface with the image memory to read data words of the image from the image memory and to write rotated data words to the image memory. The device also includes a logic module configured to interface with the plurality of buffers and to micro-rotate and macro-rotate an image based on a selection of three orientations. The logic module is also configured to execute a read of data words from the image memory to a first buffer of the plurality of buffers, a rotation of a data word, and a write of rotated data words from a second buffer of the plurality of buffers to the image memory substantially simultaneously.
