Abstract

Windows NT has become a widespread, general purpose operating system and is seeing increased use in real-time applications. However Windows NT was nor designed for real-time operation and, in such environments, the all too common Windows NT system stop event (crash or "Blue Screen of Death") can prove catastrophic. Consequently three commercial real-time extensions are available for Windows NT: Hyperkernel from Imagination Systems, INtime from RadiSys, and RTX from VenturCom. These extensions add determinism for real-time applications along with the capability for real-time applications to survive a Windows NT stop event. Each solution has a different architecture and our rests revealed that each solution has a different response to Windows NT crashes. These extensions differ in the types of stop events which can be survived the code required to survive a stop event, I/O capabilities after a stop event, and real-time performance during a stop event. However, all of these solutions allow some level of protection until the user can initiate an orderly shutdown at an appropriate time.

实时扩展能在Windows NT崩溃时存活下来吗?

Windows NT已经成为一个广泛使用的通用操作系统，并且在实时应用程序中的使用也越来越多。然而，Windows NT并不是为实时操作而设计的，在这样的环境中，常见的Windows NT系统停止事件(崩溃或“蓝屏死机”)可能是灾难性的。因此，有三个商业实时扩展可用于Windows NT:来自Imagination Systems的Hyperkernel，来自RadiSys的INtime和来自VenturCom的RTX。这些扩展为实时应用程序增加了确定性，并使实时应用程序能够在Windows NT停止事件中存活下来。每个解决方案都有不同的体系结构，我们的研究表明，每个解决方案对Windows NT崩溃都有不同的响应。这些扩展在停止事件类型、停止事件后的I/O能力以及停止事件期间的实时性能方面有所不同。然而，所有这些解决方案都允许一定程度的保护，直到用户可以在适当的时候启动有序关闭。
