ABSTRACT:
Method and apparatus of providing a display on a raster-scanned screen (1) from data stored in a video random access memory (8) having row and column addresses (6,7) for the storage elements, wherein the display area of the screen (1) is divided into a plurality of identical rectangular areas or "tiles". Addressing of the video random access memory (8) is derived by converting the screen raster-scanning signals via conversion circuits (5) such that sequential addressing of entire rows of storage elements of the video random access memory (8) corresponds to a description of all of the rectangular areas in turn, wherein the number of rectangular areas across the screen width is not equal to an integral power of 2.
