Abstract

In a conventional raster-refreshed display system, the line length of displayed data is fixed. The bit-for-pel refresh buffer is usually arranged in a binary fashion so that a simple increment of the storage address will address the next display line. There is a fixed correlation between storage address and screen coordinate. Such an arrangement is good for a fixed line length but can, and usually does, involve some unused storage locations at its X and Y extremes. Fig. 1 illustrates such an arrangement.
