嵌入式系统的运行需要可靠性和实时性的保证，因此良好的可靠性和实时性是嵌入式系统软件设计的重要标准。同时为了使软件系统的鲁棒性更强，嵌入式系统的设计需要一个非常好的软件架构。这里介绍了一种基于 MC U 平台的嵌入式系统软件架构方法。在这个方法中，事件驱动机制的引入满足了对软件架构的要求，主程序中不仅采用了优先调度机制，同时也加入了软件抗干扰措施，这些都使系统的实时性和可靠性得到了明显的提高。设计实验比较由该方法得到的软件架构与原始软件架构的实时性，得出由该方法优化后的软件架构确实具有更好的性能。

The operation of embedded system needs the guarantee of reliability and real-time performance,so the fairly good reliability and real-time performance are the important standards in embedded system design.In order to make software system more robust,the good software architecture is required in the design of embedded system.This paper introduces a kind of design method of embedded sys-tem software structure based on MCU platform.In this method,the introduction of event-driven mechanism can meet the demand of software architecture.The main program not only adopts the priority scheduling mechanism,but also addes the software anti-interfer-ence measures,which all improve the real-time performance and reliability of software system.The real-time performance is verified through designed experiment to compare the before and after embedded system software,which can conclude that the optimized embed-ded system software has better performance.
