Implement Of TCP/IP Protocol On The ARM Hardware Platform

With the increasing development of embedded technology and network technology,Embedded Internet technology has become an important field of research. As the Internet's basic agreement, TCP/IP protocol, which is practical and efficient, has become a real standard network protocol. It is the key to implement of embedded Internet technology.Based on the detection of residual chlorine in the sewage system of the need to solve the long-distance data transmission, the ARM hardware platform is proposed to implement TCP/IP protocol in this dissertation. This dissertation within the overall framework of ARM-based embedded system, the overall design from the beginning, gradually achieve the hardware platform, software design and realization of the protocol stack, lastly the final conclusions is given in the experiment; the emphasis of the thesis is introduced the TCP/IP protocol concrete realization. The system hardware platform design mainly is to ARM the nuclear chip LPC2210 composition smallest system design and to the Ethernet connection electric circuit design. In the software design, inserts real-time operating systemμC/OS-Ⅱin view of the processor LPC2210 transplant, and carries on to it disposes the system which into the system needs, builds the system's software platform. The concrete realization of the protocol stack, including the concrete realization of network interface hardware driven, the Ethernet interface modules and the realization of various agreements, and gives the overall design of the protocol stacks.Finally, the results show that on the ARM hardware platform, theμC/OS-Ⅱembedded real time operation system, which has practical significance, can achieve TCP/IP protocol, also can achieve design objectives.
