Research and Design of High-speed Serial Ethernet Communication System
In order to solve the problems of slow transmission rate,poor real-time performance and low practicability in the current serial port to Ethernet communication module,a high-speed real-time Ethernet communication scheme was designed in this paper.The scheme used FPGA as the driving platform,and combined the characteristics of Ethernet protocol stack chip CH395Q to optimize the SPI communication protocol and improved the data transmission rate.A technology of high-speed serial communication to low-speed serial communication was designed and implemented,which greatly improved the real-time of the da-ta transmission.The port data was received and sent through UDP data group frame.The test results show that the actual transmis-sion rate of SPI when transmitting data can reach 15 Mbit/s and the average packet loss rate of Ethernet communication is 0.085 2%.
