windows应用程序的实时性编程技术

Programming Technique for Real-Time Windows Programs

针对实时软件所具有的特点 ,分析了Windows操作系统所提供的多线程、动态优先级、锁定物理内存以及用户编写驱动程序在实时软件执行过程中起到的关键作用 ,提出了一种通过有效利用操作系统服务来提高实时软件实时性的新思路 ,其可行性和有效性在电荷耦合器件目标综合测量系统中得到了验证 ,在实时软件与操作系统平台的融合技术上有所突破 .

A new method to develop real-time program is put forward based on the real-time program's special features considering the windows operating system's services multithread, arising priority, locking physical memory, as well as the development of device driver to enhancing real-time program's performance. An application of object capture system using digital CCD camera is given to show the feasibility and validity of this method. It makes a breakthrough in the technique of combining the real-time program with the operating system.
