红外景象产生器中的线程同步问题研究与实现

The Research and the Realization of the Thread Synchronization in the Infrared Scene Generator

该文将Ｗｉｎｄｏｗｓ ＮＴ操作系统中的线程调度机制和应用程序中的线程同步控制方法相结合，对红外景象产生器软件系统中的各线程的性能进行了分析，研究了其典型线程之间的同步实现方法，同时提出了为提高应用程序效率而进行的改进并介绍了新系统的整体性能。实验证明，改进后的系统运行速度有显著的提高，应用程序对ＣＰＵ也实现了较高的利用率。

Combining the scheduling mechanism of threads in Windows NT with the control methods of thread synchronization in the Program,this paper studies the properties of different threads in the software named 'The Infrared Scene Generaic',and analyses the realization method to its typical thread synchronization. Moreover, in order to further improve the efficiency of the system,various measures are proposed with the total performance of the new system Presented.lt is shown that both the running speed of the new system and the utilization of the CPU are improved significantly.
