Design And Verification Of The Fiber Optic 1394 Network Node Based On SoPC

With the So C concept has become increasingly popular, and the rapid development of FPGA technology, So PC as a special embedded microprocessor systems has gradually become a new technical direction. It combines the So C and FPGA respective advantages, and have the software and hardware in-system programmable, scalable, extensible, scalable functionality. IEEE-1394 bus is developing rapidly in recent years, a high-speed serial bus, which has developed rapidly, high transfer rate, low price and so on. With a greater information carrying capacity, strong anti-jamming capability, low signal loss, security, stability and other characteristics Optical fiber communication technology are widely used in the field of communication. Combined with their individual characteristics,proposed this topic- design and verification of network node in the fibre-optic 1394 bus based on So PC.First of all this paper describes the advantages of fibre-optic 1394 bus, we analyze the background and significance of the status at home and abroad and IEEE-1394 article, proposed thesis topics and summarize the IEEE1394 protocol, a clear structure of the protocol, data communication, packet format. Second of all, It describes the optical fiber 1394 FPGA development processes and implement a detailed talk about the realization of Xilinx EDK software development process and the AS5643 protocol processing module, PCIE host interface and DMA module. At last, verification and testing of the FPGA function to achieve the demand in terms of waveform, log files, etc. This paper also describes the lack of relevance of the development, while the IEEE-1394 bus to see a brighter future, more firmly on the 1394 bus research and application of determination. and achieve high-speed data transmission, and long-distance transmission when the PHY have the speed of 400 M.This paper also describes the lack of relevance of the development, while the IEEE-1394 bus to see a brighter future, the more determined the significance of the bus research and applications.Upon completion of this project will be developed throughout 1394 So PC protocol processing module via the communication SFP Transceiver conversion module with optical fiber. Not only improves the data transmission speed and increase the amount of data transmission, but also reduce the attenuation data during transmission, so that the data can't add repeaters in case the transmission distance farther, more demanding to adapt to future work surroundings. AS5643 protocol processing module is the core of this project designed to meet the avionics system for data transfer bandwidth, deterministic and real-time performance and other requirements. It is for the IEEE-1394 b protocol was put forward on the basis of a series of cutting and limited basis. Where in the working status of each network node exchange data transfer mode is the core of the subject design. In the course of the experiment using the subject 400 M PHY chip,to achieve high-speed data transmission, and long-distance transmission.
