Abstract
A system including a rotate block including an array of bit storage units for storing image data bits of a subtile of an image to be rotated, the image data bits of the subtile being arranged in a plurality of subtile rows. The rotate block is operative to load the image data bits of each subtile row of the subtile into the array according to a subtile row load direction that is selected from a plurality of load directions based at least upon a rotate operation to be performed on the image. After loading all the image data bits of the subtile into the array, the rotate block repeatedly unloads image data bits out of the array to produce a rotated subtile. The image data bits that are unloaded from the array from each unloading operation form a subtile row of the rotated subtile.
