基于DSP和FPGA的激光加工系统控制器的设计

摘要

根据激光加工系统的工作特点和要求，以DSP芯片TMS32028335作为主控制芯片，对加工数据进行运算处理，实现插补算法；以FPGA芯片EP2C8Q208C8N为辅助芯片，利用FPGA芯片中的FIFO缓存处理好的加工信息，从而更好地满足激光加工系统的实时性要求，最终实现具备多轴协调运动及对系统状态实时监控，并且可以独立于PC机运行的控制器设计。%According to the characteristics and requests of laser-processing system,DSP chip TMS320F28335,as main control chip, is used to compute the processing data and realize the interpolation algorithm. By taking FPGA chip EP2C8Q208C8N as assistance,the processing information processed by FIFO buffer in FPGA chip EP2C8Q208C8N is utilized to meet the real-time requirements of laser-processing system. At last,the design of the controller which can execute multi-axis coordinated motion,system's real-time status monitoring and operation independent of PC was realized.
