摘要
在半实物仿真试验中,仿真系统的实时机制是前提。W indows2000是一个通用操作系统,能否直接应用W indows2000进行半实物仿真试验,是一个有意义的研究课题。该文对W indows2000系统的不可预知的中断处理、优先级机制以及进程间通信机制进行研究,并通过实验测试了W indows 2000在读ISA卡IPC5386的时间,在改进了系统实时性后,使得读卡的时间大大的减少,得到该情况下使毫秒级半实物仿真成为可能。
The real - time mechanism is the precondition of Hardware - in - the - loop（HWIL） simulation. Windows 2000 OS is a general operating system. Whether Windows 2000 OS can be used in the HWIL simulation is a meaningful research topic. There are interrupt handling, thread scheduling, event processing in the Windows 2000 OS . The paper studies the real - time mechanism Windows 2000 OS , analyses the shortcomings ,like unpredictable interrupt handling of Windows 2000 OS for real - time applications. Time spent on reading the data in the IPC5386 card is tested . After the improvement of the real - time quality, the reading time is reduced greatly, It is possible that Windows 2000 OS can be used in the HWIL simulation in millisecond level .
