Abstract
A hierarchially arranged memory system is described for a data processing system having virtual addressing. A three-level working memory is provided, along with an auxiliary memory, in a data processing system containing a secondary buffer between the main memory and a rapid buffer memory. Whereas the main memory contains all actual storage areas, i.e. the memory pages of the inactive processes which were required for the processing period just passed, the actual storage area for the successor process, independent from the operating system, is set independently by its own microprocessor.
