A video system has a processor processing of data to be displayed on a CRT monitor. A memory which is the embodiment shown is a multiport dynamic random accessed memory, stores the data therein according to X and Y coordinates. A video controller controls the transfer of data between the processor and the memory; the controller also, has included therein an X and Y address logic for providing the X and Y coordinates to the memory.
