A device comprising: an image data provider; an image processor; and an image data retriever; three buffers, wherein each buffer includes multiple memory pages; wherein during a certain period the image processor performs a read operation of image data from a first entry of a certain buffer, performs an image data processing operation on the read image data and performs a write operation of processed image data to a second entry of the certain buffer, the first entry different from the second entry; wherein a distance between the first and second entries is smaller than a size of a page of the certain buffer; wherein the second entry includes image data that was previously read by the image processor during the certain period; wherein the image processor repeats the read, image data processing and write operations until it reads at least two pages of the certain buffer; wherein during that certain period the image data provider and image data retriever are prevented from accessing the certain buffer.
