A kind of embedded CNC system based on ARM and FPGA is proposed. The core of the article is the design of software and hardware on ARM. The implementation of fine interpolation based on FPGA and the control strategy of acceleration and deceleration of CNC system is introduced. The CNC system combines high running speed and precision of ARM with the internal logic reconfigurability of FPGA, reduces the hardware costs and enhances the flexibility. The simulation and practice result indicates that this embedded control system features good real-time characteristics, low cost, and high-performance.
