摘　　要：Nucleus Plus是为实时嵌入式应用而设计的一个抢先式多任务操作系统,其95%的代码使用ANSI C写成,非常便于移植并能够支持大多数类型的处理器。本文根据容错管理软件的设计思想,提出了一种Nucleus Plus实时操作系统容错功能扩充方法,并在某航天三模冗余计算机平台上进行了验证。Nucleus Plus is a Real-time ,preemptive, multitasking kernel designed for time-critical embedded applications. Approximately 95% of Nucleus Plus is written in ANSI C. It is easy to transform and can support most types of microprocessors. We study the Fault Tolerant management software project and system fault tolerant, present a extent method for Nucleus Plus Real-time operating system fault tolerant in this paper. It was tested by triple module redundancy computer platforum in a space application.
