Abstract
An apparatus comprising a buffer circuit, a rotation circuit and a memory. The buffer may be configured to store original image data in one or more sub-matrices. The rotation circuit may be configured to (i) produce rotated data and (ii) store the rotated data in a transposed matrix. The memory may be configured to position the rotated data in the transposed matrix. The transposed matrix comprises final image data rotated by a predetermined angle from the original image data.
