摘　　要：分析了Windows NT操作系统实时性应用的可行性,结合某机载设备雷达成像处理单元的应用实例,从数据传输方式、内存管理、设备驱动程序以及应用程序等几个方面详细介绍了提高Windows NT系统实时性的具体措施,研究思路对利用Windows NT开发实时系统具有一定参考价值。The feasibility of Windows NT to real-time system is analyzed. By taking some air-bone radar imaging processing unit as example,the methods to improving Windows NT real-time performance are introduced,including DMA data transforming,memory management,device drivers design and application program. The study methods in this paper have considerable value for real-time system design based on Windows NT.
