在一个基于RTOS优先级,优先级反转
In a preemptive priority based RTOS, priority inversion
problem is among the major sources of deadline
violations. Priority inheritance protocol is one of the
approaches to reduce priority inversion. Unfortunately,
RTOS like uC/OS can’t support priority inheritance
protocol since it does not allow kernel to have multiple
tasks at the same priority. Although it has different ways
to avoid priority inversion such as priority ceiling
protocol, developers still have some difficulties in
programming real time applications with it. In this paper,
we redesign the uC/OS kernel to provide the ability to
support round robin scheduling and implement priority
inheritance semaphore on the modified kernel. As result,
we port new kernel with priority inheritance semaphore to
evaluation board, and evaluate the execution time of each
of the kernel service as well as verify the operations of
our implementation.-In a preemptive priority based RTOS, priority inversionproble

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.
