Abstract
There is described a memory system for use in a data processing system having more than one bit mapped display station. The memory system uses a single memory array for storing at least one separate full screen of bit mapped video data for each display station. A single video controller controls the process by which video data is read from the memory array and then simultaneously transmitted to each of the display stations. Furthermore, a memory access control unit coordinates use of the memory by the video controller and the data processing unit and also translates address signals generated by the data processing unit so that it can access the video data for each display station using a contiguous set of address values.
