Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a rotate block including an array of elements arranged in subtile rows by subtile columns including bit storage units for storing image data bits of a subtile of an image to be rotated, wherein 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, and repeatedly unload image data bits out of the array in only one direction transverse to the load directions to produce a rotated subtile, the image data bits that are unloaded from the array from each unloading operation forming a subtile row of the rotated subtile, each of said elements in a same subtile row above a bottommost subtile row include as input an output of one of said elements in a same subtile column of a one-prior subtile row. 2. The system of claim 1 , wherein said each of said elements includes a multiplexer, an output of the multiplexer providing an input to the bit storage units of the array, inputs to multiplexers in said same subtile row include 1) said output of said one of said elements in said same subtile column of said one-prior subtile row and 2) outputs from the bit storage units of prior columns in the same row.
