【摘要】：以太網(wǎng)技術(shù)的發(fā)展日新月異,許多工業(yè)及民品設(shè)備也都有了聯(lián)網(wǎng)的需求,而且高速的視頻傳輸更引發(fā)了千兆以太網(wǎng)的大量普及。FPGA芯片工藝的進(jìn)步為嵌入式系統(tǒng)注入了更龐大的活力,單片系統(tǒng)支持的功能越來越豐富,IP庫內(nèi)容的完善為設(shè)計(jì)人員提供了良好可靠的通用模塊,極大地縮減了開發(fā)的時(shí)間。本文以網(wǎng)絡(luò)模型的基本內(nèi)容為入手點(diǎn),從物理層開始并逐漸上升,依次介紹了模型中每一層與設(shè)計(jì)思路直接關(guān)聯(lián)的內(nèi)容,并為實(shí)際系統(tǒng)功能的實(shí)施找到了對應(yīng)的解決方案。無論是物理層的PHY芯片、MAC子層的控制器IP核,還是UDP/IP協(xié)議棧的簡化RTL描述、應(yīng)用層協(xié)議的自定制與使用,最終都化為整個(gè)系統(tǒng)架構(gòu)中不可或缺的部分。本系統(tǒng)還使用一塊DDR2 SDRAM芯片,用于完成數(shù)據(jù)緩存和丟包重傳等重要功能,彌補(bǔ)了UDP/IP協(xié)議的不足。最后,在這個(gè)搭建的模型之上,選擇實(shí)現(xiàn)了視頻播放和數(shù)據(jù)采集兩個(gè)具有代表性的應(yīng)用,為驗(yàn)證模型的正確性提供了佐助。本系統(tǒng)通過了嚴(yán)密的調(diào)試和排錯(cuò)流程,已經(jīng)能正確工作,但是仍然有缺陷和不足,這在文章的最后也有提及。
[Abstract]:With the rapid development of Ethernet technology, many industrial and civilian equipment also have the demand of networking.Moreover, the high-speed video transmission has caused the popularization of Gigabit Ethernet. The progress of FPGA chip technology has injected more vitality into embedded system.The function of monolithic system is becoming more and more rich and the content of IP library is becoming more and more perfect. It provides designers with good and reliable general modules and greatly reduces the development time.Taking the basic content of network model as the starting point, starting from the physical layer and rising gradually, this paper introduces the contents of each layer in the model directly related to the design idea, and finds the corresponding solution for the implementation of the actual system function.Whether it is the IP core of the controller of the PHY chip or the simplified RTL description of the UDP/IP protocol stack, the customization and use of the application layer protocol become an indispensable part of the whole system architecture.The system also uses a DDR2 SDRAM chip to complete important functions such as data cache and packet loss retransmission, which makes up for the deficiency of UDP/IP protocol.Finally, on the basis of this model, two representative applications of video playback and data acquisition are selected and implemented, which provides the aid to verify the correctness of the model.The system has passed a rigorous debugging and debugging process, has been able to work correctly, but there are still defects and deficiencies, which is also mentioned at the end of the article.
