基于SF0020芯片的嵌入式TCP/IP协议族设计与实现

The Design and Implementation of embedded TCP/IP Based on SF0020

结合网络监控系统控制终端应用,提出了一种基于兼容80C51的8位微控制器芯片SF0020的嵌入式TCP/IP设计方案。对TCP/IP协议族的关键环节——地址解析协议、网际协议、控制报文协议、传输控制协议,内存和定时器控制等进行了分析讨论,并提出了对标准协议族裁剪的策略。实际运行证明该协议族已达到期望的性能。

Combined with the applications of terminal for the network surveillance system, this paper presented the design of embedded TCP/IP protocol based on SF0020 chip that is compatible with 80C51.Address Resolution Protocol, Internet Protocol, Internet Control Messages Protocol, Transfer Control Protocol were discussed in detail. The control of memory and timer were analyzed finally, at last the scale of standard protocol strategy was put forward. It was proved that the performance of the protocol met the expectations.
