摘要:

前后台系统是一种常用的实时编程结构,在一般嵌入式实时系统中的获得了广泛的应用。但在课堂教学中要把前后台系统的实时特性阐述清楚并不容易,容易照本宣科,课堂气氛沉闷,流于形式。基于此,提出了一种渐进式比较教学方法,采用渐进加比较的方式阐述前后台系统的编程结构、调度策略、实时性、优缺点以及应用场合。教学实践表明采用渐进式比较教学方法明显提高了教学效果。

Abstract:

Fore-back system is a commonly used real-time programming structure, and has a wide range of applications in embedded real-time systems. But in the classroom it is not easy to clearly set forth the characteristics of the fore-back system, and it is easy to bore classroom atmosphere. This paper presents a progressive compare teaching methods, which could clearly describe the fore-back system about programming structure, scheduling policy, real-time characteristics, advantages and disadvantages, and applications. Teaching practice shows that the progressive compare teaching method could improve the teaching effect.
