Design And Implementation Of Embedded Ethernet Interface Based On SMQ2V6000

With the development of embedded technology and ethernet technology,the application of ethernet interface in embedded system is more and more extensive,embedded devices has been successfully infiltrated into various industries,various fields,and gradually toward networking,intenlligent direction of development.ethernet communication interface developed into a mature method with its excellent performance in real-time,reliability,standardization and other adpects.as well as its advantages of easy installation,esay maintenance and free from the limitation of communication distance.Embedded ethernet interface products are widely used due to their low cost,communication protocol standaed and ease of maintenance.However most of the research and design of embedded ethernet interface products are based on foreign chips,which have low degree of self control and control and have security risks.With the increasing development fo China's comprehensive national strength,the application of domestic chips is becoming more and more extensive.especially in some special industeies the requirements for the localization of equipoment are more and more strict.Therefore,it is necessary to adopt standard network communication protocol to design the embedded ethernet interface with excellent performance and self control,to form a stable and reliable embedded ethernet interface product to meet the needs of embedded network communication in special industeies.Therefore,this paper combed the implementation methods of embedded ethernet interface,analyzes the domestic and foreign research of the embedded ethernet protocol starck and ethernet interface chip.by the principle of “self controlled,safe and reliable,strong performance,low power consumption”,based on the application requirements of special industeies,the implementation scheme based on domestic FPGA chip without embedded operating system is adopted to fundamentally solved problem such as low self controllable and potential safety problems.the design and implementation of embedded ethernet interface sofeware/hardware based on domestic chip was carried.the functional performance was tested,and the expected results were achieved.The main work includes the following parts:1?Combing through the implementation methods of embedded ethernet interface at home and abroad,Comparison and analysis the domestic and international mainstream embedded ethernet protocol starck and ethernet interface chip.2?Analyzed the application requirements of embedded ethernet interface in special industeies,selected the implementation scheme based on the domestic FPGA chip SMQ2V6000 without embedded operating system,carried out the general plan design,and made full use of The characteristics of FPGA to improve product preformence.3?Carried out the embedded ethernet interface hard design based on domestic chip,including,including principle diagram design,PCB design and production debugging.And soft design,mainly includes the ARP,ICMP,UDP and TCP protocol parsing and processing,completed the debugging and testing of embedded ethernet interface and the next step is prospected.
