摘要
目前嵌入式操作系统的应用越来越广泛,不仅增强了系统的可靠性,而且提高了开发效率。但是,在对实时性要求较高的应用中,对于基于软件实现的RTOS,单纯依靠改进算法已不能使其实时性得到更大的提高。而硬件电路独立于处理器运行,不占用处理器的处理时间,所节省的时间可用于执行任务程序,所以基于硬件实现的操作系统可以使它的实时性和可靠性显著提高。
Embedded operating system is used more and more widely,which not only improves the reliability of the system but also im proves the development efficiency. The RTOS based on software is used for the applications that demand higher real-time, however the improved algorithm can not increase the real-time greatly. Because the hardware circuit is independent of the processor,and do not take up the processing time, so the saved time can execute the task program. The operating system based hardware implementation can make real-time and reliability improved significantly.
