从结构上来说，实时多任务操作系统包括两部分，一部分为操作系统内核(kernel)，即实时执行程序(Real Time Executive:RTX)，另一部分是输入输出部分(I/O)(注意开发系统不属于操作系统的范畴)；嵌入式系统对I/O的需求通常比较小(无文件系统需求)，因此很多实时多任务操作系统本质上就是一个实时执行程序，如AMX(Kadak)，VRTX(Microtec)，iRMX(Intel)等(这里的X即:eXecutive)，如果纯粹从kernel的角度来考察目前流行的各种实时多任务操作系统的性能，它们的效率差别都不大。
在市面上可以得到一些RTX的源代码(有用C实现的，有用汇编实现的，还有用PL/M语言实现的)，从internet上也可以荡一些下来(我介绍一个站点www.eg3.com，堪称世界电子工程师资源宝库)，下面我要介绍的一个RTX版本(我命名为SRTX:short RTX)，可以说是RTX中的元老级产品了，来自某研究所，九十年代初他们到美国考察，从美国某公司购得。五年以前，SRTX在国内有售，许多搞工控的研究所利用SRTX开发了一些大型或小型的产品,这里介绍的SRTX我作了一些简化和改动.
