Abstract
A device and method for data image processing. The method includes writing, image data to a certain buffer by an image data provider; characterized by repeating steps of reading, by an image processor image data from a first entry of a certain buffer, processing the image data by the image processor, and writing processed image data to a second entry of the certain buffer; wherein the repeating ends when at least two memory pages of the certain buffer are read; wherein a distance between the first and second entries is smaller than a size of a page of the certain buffer and conveniently much smaller than the size of the page; wherein the second entry includes image data that was previously read by the image processor during the certain period; and preventing an image data provider and an image data retriever form accessing the certain buffer during the repetition.
