A hardware platform with“ARM+FPGA”architecture and a software platform based onμC/OS-Ⅱreal-time operating system were designed for NC carving machine. For the hardware platform,due to the high computing performance of the ARM micro-processor and high logical processing performance of the FPGA,both the number of the peripheral components and the design complex-ity were reduced. For the software platform,using μC/OS-Ⅱembedded real-time operating system,not only multiple tasks could be done concurrently,the real-time character and stability of carving machine motion control was guaranteed,and the high speed and precision processing requirements were met,but also the system had a good man-machine interface.
