Abstract
The invention is a method and apparatus for processing image data stored in a memory. A read interface circuit is coupled to the memory to transfer a patch of the image data from the memory to a buffer. A scale filter is coupled to the read interface circuit to scale the image data in the patch from the buffer. A receive circuit is coupled to the scale filter to re-organize the scaled image data.
