INPUT/OUTPUT IN TIME-SHARED, SEGMENTED, MULTIPROCESSOR SYSTEMS.
Abstract
After introducing and defining the concepts of time-sharing, segmentation, and multiprocessing, two classes of systems incorporating these are introduced. Both classes use associative memories, as 'look behind' devices to speed the operation of addressing the segmented memory, with the distinction between classes being the location of the associative memory. In one class, there is one associative memory for each processing element, no matter how many main memory units are connected to a processor; in the second class, there is one associative memory for each main memory unit, with the processors sharing the associative memory. After introducing two criteria for input/output systems, that the overhead associated with their use be small and that they may be physically and logically simple, and describing further operations of the systems, it is concluded that members of the second lass, having shared associative memories, best meet these criteria.
