摘　　要：用双软核心处理器设计出XYZ平台运动控制系统。采用双Nios II软核处理器,分别用于处理与上位机的通信接口和对指令的编译、译码及前瞻处理。开发硬件插补模块作为协处理器,完成精插补和自动加减速等功能。该控制系统可实现两轴或三轴直线插补,任意两轴圆弧插补。采用多核SOC并行处理提高了系统的插补精度和进给速度。XYZ platform motion control system was designed using Dual-soft core processor. It adopted the Dual-soft core processor of Nios Ⅱ, which was used respectively for the communication interface with upper computer and for compiling, translation and prospects treatment of the code. Hardware interpolation module, as a coprocessor, can complete interpolation and automatic acceleration-deceleration. The control system can achieve linear interpolation of 2-axis or 3-axis and circular interpolation of any 2-axis. The accuracy of the interpolation and feed rate are improved by using multi-core parallel processing of SOC.
