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.
