Design and Implementation of Gigabit Ethernet Communication Moule for Motion Controller Unit
A gigabit Ethernet implementation scheme based on field programmable gate array(FPGA)was proposed to ad-dress the issue of traditional communication methods not meeting the transmission speed and real-time requirements of motion controllers.Combining the encapsulation and parsing process of data frames in the UDP/IP protocol,an integrated design was car-ried out for the MAC layer,IP layer,and UDP layer to achieve a low-cost gigabit Ethernet communication module.After simula-tion and hardware testing,the main frequency of this module can reach up to 179.76 MHz,and the interval between data frame reception and transmission was only 444 ns,and memory usage was less than 1％,which met the transmission rate and real-time requirements of gigabit Ethernet.In addition to the normal Ethernet communication function,it can also achieve data frame clear-ing and resending functions,as well as dynamically configure the IP and MAC addresses of the communication module,providing a low-cost solution for Ethernet communication of motion controllers.
