摘要
通过对Windows95／NT加以改进，使其适应CNC系统的强实时性的要求，按照CNC系统任务的实时性要求的不同，把它们分为严格实时性任务，准实时性任务和非实时性任务，并提出了相应的调度策略，以关键区作为数控芯片之间的数据传输的桥梁，在关键区中对数据进行排队。这种方法可以用来提高数控系统的性能和对系统的调度策略进行优化。
Windows95/NT systems are improved to adapt for the CNC system's real - time reqirement. According to the diffircnce of the real time demands of the Software IC, they are divided into three sections:exact - real - time tasks,semi real - time tasks and no - real - time tasks. The soheduling strategy of the tasks is provided. The critical sections are used for the bridge of data exchanging among the Software IC,and the data are queued in the critical sections. This method can be used to improve CNC system and optimize the scheduling strategy.
