This paper discusses a hardware and software architecture of embedded numerical control system. This system is built on uCOS-II and ARM. The liming specification of uCOS-II is analyzed based on the performance of RTOS. The method for getting the longest timing specification of uCOS-H is described. And the time of system schedule is measured. The paper also analyzes the system real-time performance and stability. The result indicntes that this embedded numerical control system has perfect real-time character, low cost and high-performance. It has extensive application. |
