摘　　要：随着实时嵌入式技术的发展,越来越多的实时系统采用Windows操作系统平台。为了满足实时系统严格的响应时间要求,增加Windows操作系统的实时能力非常必要。进程间的通信是任何一个实时操作系统中必不可少的一部分,在此分析Windows操作系统原有进程间通信的弊端,提出改进方法,在Windows操作系统上减少进程间通信所消耗的时间,提高进程间通信的效率。With development of real-time embedded technology, the operating system platform of Windows series is increasingly adopted by real-time systems. To meet the strict request of response time for real-time systems, it is necessary for Windows operating system to add its real-time ability. Since the inter process communication （IPC） is an absolutely essential part of any real-time operating system, the original IPC disadvantages of Windows operating system are analyzed, and an improvement method is proposed. That is, the time consumed by PIC is reduced in Windows operating system, and the efficiency of IPC is enhanced.
