为什么RTOS codeD只能在C？ [英] why are RTOS coded only in c?

问题描述

是否需要code RTOS中始终C语言？为什么不能说是在Java codeD或其他一些技术..？那是因为在java中没有指针的概念呢？

Is it necessary to code RTOS in C language always? Why can't that be coded in java or some other technology..?? Is that because of the absence of pointer concept in java?

推荐答案

垃圾收集是在Java是实时的重要原因。 JIT是另一种的，但它是可以克服的。

Garbage collection is the big reason against Java being Real Time. JIT is another, but it could be overcome.

虽然在一般，C是有效的便携式组装给人很predicable运行时的性能，这是可靠的实时执行的关键。

In general though, C being effectively portable assembly gives very predicable run-time performance, and that's essential for reliable real-time execution.
