Microsoft公司在UNIX SYSTEMⅢ基础上发展了一种类似的操作系统——XENIX配在16位高档微机系统中。目前国内外,在中小型计算机及微机系统中都普遍地使用UNIX和雷同UNIX的操作系统。本文从系统设计角度,对操作系统核心部分的存贮管理和存贮保护作一综合性的论述。结合较典型的16位微机系统—Intel的86/330X,对存贮器怎样进行管理,怎样进行保护,以及系统软件中需要考虑的一些问题等方面作了描述。对了解和分析多用户分时操作系统(XENIX)的核心提供参考。
Microsoft developed a similar operating system based on the UNIX SYSTEM III - XENIX with 16-bit upscale microcomputer systems. At home and abroad, UNIX and UNIX operating systems are commonly used in small and medium-sized computers and computer systems. This article from the system design point of view, the core of the operating system storage management and storage protection for a comprehensive discussion. In this paper, the typical 16-bit microcomputer system-Intel 86 / 330X is described in terms of how to manage the memory, how to protect it, and some problems to be considered in the system software. For understanding and analysis of multi-user time-sharing operating system (XENIX) to provide a reference core.
