Abstract: A memory control unit adjusts and sets the address of an image data area in the memory space of a memory and the address of a window area adjacent to the memory area, using a memory controller. The memory control unit stores data, other than image data that is supplied, at a specified address location and, when a control signal is sent to the memory, reads out the image data, including data stored in the window area, from the memory. The data that is read out from the window area is inserted into a predetermined position during a blanking period.

Abstract: A display device is disclosed that includes a cache memory consisting of memory segments, each memory segment being capable of storing an image fragment. A video generator is driven by a video cache reader, which builds up a screen image from complete or partial image fragments stored in the memory segments. By means of hardware counters and registers the address of an image point in the cache memory is derived from the address of the image point read in last. As a result of this, the screen image can be built up very rapidly, so that no special screen memory is required and the amount of data to be transferred is reduced.
