Abstract
An image processing system is described in which a data buffer memory,is provided between an image processor,and an image frame memory,The data buffer memory,stores a sub-set of the raster lines stored within the image frame memory,. This data can be read in either an intra-raster-line mode from adjacent memory cells within a bank or in an inter-raster-line mode from memory cell locations at corresponding positions within different banks. The data may be 8-bit pixel data or 16-bit pixel data. In the case of 8-bit pixel data a single bank contains a full raster line whereas in the case of 16-bit pixel data a single raster line extends over two banks.
