Abstract

This article describes the achievement of a reduction in storage requirements and program development effort in a system which consists of two dissimilar operating systems by consolidating similar functions from each and implementing them only in one or the other operating system. Fig. 1 illustrates a system which consists of two dissimilar operating systems executing on processors efficiently coupled through a Direct Memory Access (DMA) interface. System storage requirements and program development effort are saved by consolidating similar system services from each operating system into one system or the other and eliminating duplication except where justified by performance considerations.
