安全关键嵌入式系统中显示系统的资源？
我正在寻找可以回答我的以下问题的资源。
- SC ERTS架构中的显示系统到底适合哪里？
- SC显示系统与普通显示系统有什么区别？
- 硬件和软件在显示系统中扮演什么角色？
我必须为我的课程作业准备一份关于显示系统的详细调查。请注意，我要求的是参考资料、来源等，而不是实际的答案。
我也很乐意看到肢体的建议和评论。
我已经发现一些有用的东西：DO 178B 标准、SCADE 显示系统。
I am looking out for resources that can answer following questions of mine.
- Where exactly does the display systems in SC ERTS architecture fit in.
- What is the difference between SC display systems and normal ones?
- What roles does hardware and software play in display systems?
I got to prepare a detailed survey of display systems for my course work. Please note that I am asking for references, sources etc and not the actual answers.
I will also be happy to see off the limb suggestions and comments.
Something useful I already found : DO 178B standard, SCADE Display Systems.

安全关键显示系统与普通显示系统之间的区别与任何安全关键系统与相应的非关键系统之间的区别相同：它是安全关键。这种系统的一些故障可能会危及安全。因此，这些系统是按照严格的流程设计、实施和测试的，通常流程本身需要经过认证（您已经找到了 DO-178B - 对于航空软件，其他领域也存在其他类似的标准。其他标准经常发现适用于多个领域的工具制造商与 DO-178B 一起提及的是 IEC 61508、EN 50128 和 ISO 26262。
我不知道为什么你期望任何东西专门适用于显示系统......你的问题对于这里的公众来说可能太具体了。
请注意，一般来说，安全性与可靠性不同。安全关键系统不必完全可靠，只需了解其可能发生的故障，并证明其不会危及安全。这一原则在不同的关键领域有不同的应用：允许火车发生故障，而飞机则不允许。
The difference between a safety critical display system and a normal one is the same as between any safety critial system and the corresponding non-critical one: it's safety critical. Some failures of such a system could endanger safety. As such, these systems are designed, implemented and tested following a strict process, typically with the process itself being subject to certification (you already found the DO-178B -- for software in aeronautics, other similar standards exist for other domains. Other standards often found mentioned together with DO-178B by the makers of tools that apply to several domains are IEC 61508, EN 50128 and ISO 26262).
I'm not sure why you expect anything to apply specially to display systems... Your question may be too specific for the public here.
Note that generally speaking, safety is different from reliability. A safety critical system doesn't have to be perfectly reliable, only its possible failures have to be understood and to have been shown not to endanger safety. This principle applies differently in different critical domains: trains are allowed to fail in ways planes aren't.
