摘　　要：针对传统简单文本传输协议(TFTP)客户端文件传输系统的以太网开发存在编码复杂和传输不稳定等问题,设计了一种基于以太网芯片W5300的TFTP客户端文件传输系统。系统软件架构采用模块化的现场可编程门阵列(FPGA)编码设计理念,利用W5300的硬件协议栈,将以太网开发简化为有限的寄存器读写。同时,在流程设计中引入多维的超时重传等处理机制,最终实现了稳定可靠的文件传输。Aiming at the problems of complex coding and unstable transmission in the Ethernet development of traditional TFTP(simple file transfer protocol) client file transmission system, a TFTP client file transmission system based on Ethernet chip W5300 was designed.The system software architecture adopted the modular FPGA(field programmable gate array) coding design concept, and simplified the Ethernet development into limited register reading and writing by using the W5300 hardware protocol stack.At the same time, multi-dimensional overtime retransmission and other processing mechanisms were introduced into the process design, and finally a stable and reliable file transmission was realized.
