摘要
普通微型计算机由于各种相互兼容的标准硬件及丰富的应用软件支持而获得了广泛的应用,但它们之上往往都是运行多任务、多用户的Windows操作系统,一般不能满足半实物仿真的实时性要求。详细介绍了一个Windows平台下的实时仿真计算机系统PCRTSim,重点研究了PCRTSim下的实时时钟获取问题、帧时间不稳定问题,提出了保证实时仿真帧时间的具体思路,并通过一个简单例子探讨了PCRTSim的具体应用。
General-purpose computer,supported by all kinds of compatible standard hardware and plenty of application softwares,
has been most wildly used in the world.However,it cannot meet the need of real-time simulation in a general way since the
operating system always runs on those multi-tasks,multi-users Windows 9x/2000.Firstly,PCRTSim was introduced that is a
kind of real-time simulation computer system based on Windows in details.Secondly,the acquiring of high-resolution real-time
clock and the stability of frame-time under general-purpose OS environment at length was discussed.It not only presented several
methods to carry out real-time simulation on general-purpose computer,but also taught users how to use PCRTSim by a simple
application example.
