摘要
本文简要介绍了传统的单态和两态结构操作系统，分析了微内核结构操作系统中采用两态结构仿真传统操作系统ＡＰＩ界面的不足。最后介绍了多态操作系统的思想及其在国产操作系统ＣＯＳＩＸＶ２．
In the first part of this paper,we briefly discuss the traditional single level operating system and two level operating system.Then,we present some problems in the microkernel operating system based on two level structure,those problems are the main causes of some operating system bugs in emulating traditonal OS application programming interfaces(or API).Finally,we introduce an idea about the multi level operating system to resolve these problems,and give out the implementation of this idea in COSIX V 2 0 ,a chinese copyright operating system.
