摘　　要：本文提出了在 UNIX 操作系统中,将共享内存和队列结合起来,采用共享内存来进行进程间的数据通信,用信号灯来同步共享内存区,应用共享内存队列来解决进程间通信数据量过大并且传递的频率过快的问题,文中介绍了进程间通信、共享内存区、信号灯以及队列的基本概念和在 UNIX 中的具体操作函数,详细说明了共享内存队列的具体实现算法。This paper proposes to combine shared memory and queue in UNIX operating system, and use shared memory to realize inter-process communication, use semaphore to synchronize shared memory area, and use shared memory queue to solve the problems of over data volume of inter-process communication and over fast transmission frequency. The paper introduces the basic concepts of inter-process communication, shared memory area, semaphore and queue and their specific operation functions in UNIX, and describes in detail the specific implementation algorithm of shared memory queue.
