说明：  1． 经典IPC问题的分析报告 根据课本所提供的几个实例或自己查找到的IPC实例，写出具体的模型的设计思想，写出相应的伪代码，并针对于伪码写出具体的设计思路，每个信号量的设置含义及目的，并对于设计的每行伪码给出详细地解释，对其可能被中断情况给与分析。（如有可能，可以利用多线程编程对某个算法具体实现）
(1. IPC classic analysis of the textbooks in accordance with the provision of several examples or to find their own examples of the IPC, write specific model of the design ideas, write the corresponding pseudo-code and address to write pseudo-code specific design ideas, each set of signal meaning and purpose and design for every trip PN code is explained in detail, which may be given in case of interruption analysis. (If possible, can take advantage of multithreaded programming algorithm for a specific realization))
