Abstract
A relatively high speed circular memory device, in combination with other processes, improves image processing efficiency. To that end, a method and apparatus of processing image data stored in an initial memory logically divides the image into a plurality of contiguous strips. A first plurality of the strips are stored in a working memory having a circular addressing arrangement, where the working memory is faster than the initial memory and has a plurality of sequential address locations. The first plurality of strips are contiguous and have a start address. In addition, the first plurality of strips are stored in the working memory in a contiguous manner, and processed through the working memory relative to the start address.
