基于TOE技术的嵌入式以太网接口设计

摘要

为减轻主机CPU对TCP/IP协议栈处理的负担,提高嵌入式系统的性能,该文提出一种基于TOE (TCP/IP Offload Engine)技术的嵌入式以太网接口设计.该设计介绍了一种通过硬件来实现协议栈处理的方法,利用具备协议处理能力的网络控制芯片W5300,在TCP协议的基础上实现了嵌入式系统的以太网接入.%In order to reduce the burden of host CPU for TCP/IP protocol stack processing and improve the performance of embedded systems, proposed an embedded Ethernet interface design based on TOE (TCP/IP Offload Engine) technology. This design describes a hardware implementation of the protocol stack processing methods, using the network control chip W5300, which has the ability of protocol processing, achieved the Ethernet access in embedded systems based on TCP protocol.
