摘要： Provided is an image rotation method and apparatus for rotating an original image of 2n×2n pixels when n is a natural number greater than 1, including loading each row of pixels of the original image into a corresponding load memory vector; and, after the load step, for at least one iteration, performing a transposition operation for each matched load memory vector after matching the load memory vectors and, for zero or more iterations, an interleaving operation between each matched load memory vector after matching the load memory vectors, while the transposition step and the interleaving step are performed a total of n iterations.
