摘要
并发进程的控制管理是操作系统课程中的核心内容,其中同步互斥问题一直是教学中的难点。针对学生普遍反映使用信号量机制解决并发控制问题难度大、题目灵活多变、不易求解的问题,本文提出流程驱动的算法设计解决同步互斥问题,结合具体题目,详细叙述了该方法的实际应用。课堂实践表明,这种方法易于掌握,对于大多数同步互斥问题,借助此法可以得到正确有效地解答。
Control and management of concurrent process is the main content of operating system where process synchronization ＆ mutual exclusion is always the difficulty in teaching. In order to help the students cope with the variability and solve the problem correctly, the paper presents a procedure-driven method on the solution of process synchronization ＆ mutual exclusion. Specific example is given to show how this method is used. Teaching practice illustrates that the method is effective and can be easily grasped.
