摘　　要：在网络飞速发展的今天,计算机网络设备成为系统的瓶颈。运用通用处理器处理协议的终端很难适应当前的网络速度,同时网络协议的复杂性,需求的高效性、多样性,验证的复杂性等诸多因素,增加了TCP/IP开发难度。研究了嵌入式系统中TCP/IP实现方法,研究传统协议处理性能瓶颈,结合SOPC特点,提出基于SOPC的在线流模式下处理架构,通过DMA、扩展指令、网络协处理器、配置选项等方法,提升网络了处理性能。As the speeding development of network, the power of network equipment to process TCP/IP stacks has already became the bottleneck. To use general process of terminal is difficult to adapt to current net speed,and many factors increase the difficulty of TCP/IP exploitaion,such as complexity of protocol,high efficiency and diversity of demand,complexity of examining. This paper researches the realization method of TCP/IP on embedded system,studies the traditional protocol processing bottleneck and integrat the SOPC charcter, advances to on flying processing structure through the DMA,extends instrcion, net protocol coprocess,configuration to speed the network.
