摘要

嵌入式系统采用硬件和软件相结合的方式进行控制。它们通常由执行存在于ROM中的指令的微处理器/微控制器处理。术语“嵌入式”反映了它们是系统的一部分这一事实。实时操作系统(RTOS)结合了“实时”和“操作系统”两个思想。在这些操作系统中,性能取决于逻辑结果和获得结果的时间。运行实时应用程序的操作系统称为RTOS,当然在所需的时间框架内提供结果。其工作过程与普通操作系统几乎相同,但也提供了允许实时调度任务的功能。RTOS不会提高执行速度,但它比一般的操作系统更精确。

Real-time issues in embedded system design
The Embedded system is controlled with the combination of hardware and software. They are usually processed by a microprocessor / microcontroller that execute instructions which are present in ROM. The term "embedded" reflects to the fact that they are part of the system. Real-Time Operating System (RTOS) combines with two thoughts "real-time" and "operating system". These are the operating system where the performance is based on the logical result and the time at which the results are obtained. The operating system called as RTOS running real time applications provide the result of course in the required time frame. The working procedure is almost the same as normal operating system, but also offers to allow the real time scheduling tasks. The RTOS is not going to increase the speed of execution, but it is accurate than the general OS.
