【摘要】：射頻識別(Radio Frequency Identification,RFID)技術(shù)的出現(xiàn)可追溯至20世紀(jì)40年代,經(jīng)過相當(dāng)時間的發(fā)展,于20世紀(jì)90年代興起。作為自動識別技術(shù)的一種,被譽(yù)為21世紀(jì)最具創(chuàng)造性和發(fā)展前景的信息技術(shù)。近年來隨著信息社會的不斷發(fā)展,RFID技術(shù)正扮演著愈發(fā)重要的角色。超高頻(Ultra High Frequency,UHF)RFID技術(shù),作為RFID技術(shù)中的一員,工作在射頻頻段,具有高速傳輸、遠(yuǎn)距離多目標(biāo)識別等優(yōu)勢,目前已經(jīng)成為國內(nèi)外研究和應(yīng)用的熱點,在未來勢必成為信息社會的重要組成部分。傳統(tǒng)的ASIC系統(tǒng)芯片的設(shè)計,需要較長的研發(fā)周期以及較大的成本,隨著微電子技術(shù)的不斷發(fā)展,半導(dǎo)體工藝的不斷革新,以及市場需求所帶來的沖擊力,傳統(tǒng)的設(shè)計流程已難以跟上步伐。因此,基于IP(Intellectual Property)核的SoC(System on Chip)設(shè)計方法開始流行。SoC技術(shù)可以有效集成多個IP核,實現(xiàn)復(fù)雜的系統(tǒng)功能,同時可以較好地降低功耗、尺寸等關(guān)鍵因素,加快產(chǎn)品的研發(fā)周期,降低研發(fā)成本,逐漸成為集成電路設(shè)計的重要方向之一。本文基于ISO/IEC 18000-6C協(xié)議,采用SoC的設(shè)計方法,劃分軟硬件模塊,采取軟硬件協(xié)同設(shè)計的方法設(shè)計了UHF RFID系統(tǒng)的數(shù)字基帶處理單元。選取開源處理器MC8051,采用Verilog硬件描述語言設(shè)計完成UHF RFID基帶通信鏈路模塊,并通過WISHBONE總線協(xié)議將其作為獨立的IP核與MC8051互連,實現(xiàn)系統(tǒng)硬件的設(shè)計,并在MC8051中完成協(xié)議部分算法的實現(xiàn),最終實現(xiàn)閱讀器與標(biāo)簽基帶的通信,完成系統(tǒng)的驗證。
[Abstract]:RFID (Radio Frequency Identification (Radio Frequency Identification,RFID) technology can be traced back to the 1940s. After a long period of development, it rose in the 1990s. As a kind of automatic recognition technology, it is praised as the most creative and developing information technology in the 21st century. In recent years, with the development of information society, RFID technology is playing an increasingly important role. UHF (Ultra High Frequency,UHF) RFID technology, as a member of RFID technology, works in RF frequency band, has the advantages of high speed transmission, long distance and multi-target recognition, and has become a hot spot of research and application at home and abroad. In the future is bound to become an important part of the information society. The design of traditional ASIC system chips requires a long research and development cycle and a large cost. With the development of microelectronics technology, the continuous innovation of semiconductor technology, and the impact of market demand, The traditional design process has been difficult to keep up with the pace. Therefore, the SoC (System on Chip) design method based on IP (Intellectual Property) kernel is becoming popular. SoC technology can effectively integrate multiple IP cores, realize complex system functions, and reduce power consumption, size and other key factors. Speeding up the R & D cycle of products and reducing R & D costs are becoming one of the important directions of IC design. Based on the ISO/IEC 18000-6C protocol, the design method of SoC is used to divide the software and hardware modules, and the digital baseband processing unit of the UHF RFID system is designed by the method of hardware / software co-design. The open source processor MC8051, is selected to design the UHF RFID baseband communication link module with Verilog hardware description language, and it is interlinked with MC8051 as an independent IP core through WISHBONE bus protocol to realize the hardware design of the system. Finally, the communication between reader and tag baseband is realized, and the verification of the system is completed.
