Design and Realization of Motion Control Board Based on DSP and FPGA

To the characteristics and requirements of the CNC system,and based on analyzing the functions and traits of DSP chip TMS320F2812,and FPGA chip EP1K30,the design and realization of movement control board based on DSP and FPGA are presented.The design adopts DSP and FPGA to replace microcontroller under full considerations of their resources and traits,and can better fulfill the requirements of motion control on precision and real-time ability.A certain three-axis simulation turntable has adopted the movement control board as the main control board,and perfectly realized the requirements on the precision of position,velocity,etc.
