| 摘 要： | 时钟精度直接影响到实时任务能否被及时响应和调度,数控系统要求其软件平台能提供微秒级的时钟精度。Linux操作系统由于其开放源代码的特点,非常适合开发具有自主产权的全软件数控系统,但是其毫秒级时钟精度明显过于粗糙。结合上述方法,提出一种混合多种时钟模式的动态时钟系统,提高Linux的时钟精度。通过仿真测试证明能满足数控系统的要求。

| Abstract: | Clock-precision affects directly that whether the real-time task can be responded timely and scheduled,CNC system requirements its software platform to provide clock-precision of ms-level.Because the characteristics for Linux operating system is free source,it is an ideal for development of numerical control system with independent property rights,but the ms-level clock precision is too rough.Combination of the above methods,a dynamic-clock system of hybrid multi-clock model is proposed to improve Linux clo... |
