Abstract
The present invention is a system architecture and methods of operation which reaps all the advantages of patch access processing while allowing many important types of image manipulation to be performed to the granularity and addressability of a single pixel. It goes beyond conventional concepts of the limits of pixel granularity by manipulating pixel data across and within bit planes in a manner which enables bit positions to be exchanged within the same pixel and/or swapped between different pixels.
