摘　　要：嵌入式系统接入Internet已经成为一种需要,若要实现Internet接口必须在其上运行TCP/IP协议栈,而由于嵌入式系统的资源有限性,若选择高端处理器来解决这个问题,显现增加了系统的成本,因此采用了将TCP/IP协议栈裁剪,尤其是TCP协议约简的策略,得到了嵌入式MINI TCP/IP协议栈,该协议栈在不改变接口的情况下节约了RAM空间,提高了系统性能,将其运行在8位微处理器上,可实现小型嵌入式设备低成本的接入Internet.People need an embedded Internet access system is necessary.The TCP / IP protocol stack must be run on the embedded system in order to realize Internet interface.Because of limited resources in embedded system,if you choose advanced processor to solve the problem,obviously the cost of system is increased.So the method that the TCP/IP stack and especially the TCP protocol are reduced is adopted,and the embedded MINI TCP/IP protocol stack is formed.The stack can save RAM space in the case of not changing the interface,and the capability of system is increased.That the embedded stack is run on 8-bit microprocessor can realize the small embedded device accesses low-costly to Internet.
