基于FPGA的TCP/IP网络通信系统的设计与实现
Design and implementation of TCP/IP network communication system based on FPGA
摘要
Abstract
In allusion to the disadvantage that the pure software must rely on the operating system for network communica-tion implementation, and is prone to attack, a TCP/IP network communication system based on FPGA technology is designed and implemented by using the pattern of controlling the W5500 protocol stack chip. In the system,the network disconnection auto-matic reconnection function is added,and the CRC redundancy error check is used to discern the data and achieve the filtering of illegal data. The design scheme of the system is introduced,and the system is tested with the evaluation indexes of frame loss rate,bit error rate and transmission speed. The test results show that the system can transmit data accurately and the data trans-mission rate is high.关键词
