【摘要】 为研究有限状态机分析法在嵌入式系统教学中的效果,将其引入到基于嵌入式系统的计算器设计中.利用状态机思想,分别对普通计算器和带有优先级的计算器进行建模和设计.详细叙述建模基本步骤,分析不同状态的含义以及状态间的转换条件.通过对比教学用时,学生完成率和编程所用代码量等指标,比较了流程图法和有限状态机法的教学效果.实验结果表明,利用有限状态机分析法设计计算器的教学效果明显优于流程图法.更多还原

【Abstract】 To reaserch the teaching effect of the finite state machine analysis method in the embedded system lesson,the finite state machine was introduced in the design of the calculator based on embedded system.By using the idea of the finite state machine,the ordinary calculator and the calculator with priority were modeled and designed.After a detailed description of the basic steps of modeling,the meaning of different states and the transition conditions between states were analyzed.By comparing the teaching time,students completion rate and the amount of programming code and other indicators,the teaching effect of flow chart method and finite state machine method were compared.The experimental results show that the teaching effect of using finite state machine method is obviously better than that of using the method of flow chart designing calculators.更多还原
