摘　　要：针对传统嵌入式设备中以太网传输速度慢的问题,研制了一种基于FPGA和W5100的高速以太网实现方案.采用SOPC技术配置NiosⅡ处理器,控制硬件TCP/IP协议栈W5100芯片实现设备的以太网传输,并利用C2H对W5100中的关键C代码进行硬件提速.该系统传输数据可靠,传输速度较传统实现方法有显著提高,实现了系统的高速网络传输.In order to solve the question of slow speed Ethernet transmission in traditional embedded equipment, an implement method based on FPGA and W5100 was designed. The Nios Ⅱ processor which was created by SOPC technology was used to control hardware TCP/IP protocol WS100 to realize Ethernet transmission, and C2H was used to do hardware accelerator for crucial C code. This system transmits data reliably and has much faster transmission speed than traditional methods, realizing high-speed Ethernet transmission.
