The Design and Realization of Motion Controller Based on DSP and FPGA

For the characteristics and requirements of CNC system,having in-depth analyzed functions and features of TMS320C6713 DSP chip of TI and A3P400 FPGA chip of ACTEL,presents a design and realization of motion controller based on DSP and FPGA.Based on taking full account ofthe chip's characteristics and resources,the controller uses floating-point DSP and FPGA,to better meet the requirements of real-time motion control unit and the control demanding precision for CNC system.The motion controller hardware structure and the detailed design of the main modules are introduced,and also gives the program structure of DSP software framework.
