Advanced Operations Support System (AOSS) for Small Computers.

Abstract

AOSS is an operating system designed to bring to small computers power and sophistication normally found only in operating systems for much larger computers. It uses a segmented virtual memory to allow efficient use of large programs in a small memory and to provide memory protection between concurrent tasks which are allowed to interact only through a set of effective but rigorously defined communications commands. This allows a high degree of task interaction without a complicated control program. AOSS may operate in dedicated, time-sharing, or multi-programming mode simply by altering one program module. The rigorous segmentation of memory and the strict control task interaction allows AOSS to be spread across a net of computers without seriously altering the environment of any particular task. This capability has great possibilities for a variety of systems. A quite promising one is a large-computer small-computer network where the small computer handles most of the interactive tasks and the large computer handles most of the compute-bound tasks.
