[Abstract]:In recent years, with the continuous development of communication technology and integrated circuits, the processing speed of digital signal processing system is increasing rapidly, which also puts forward higher and higher requirements for the communication bandwidth of the front end. The traditional communication interface (parallel bus RS232 interface RS485 interface, 100-megabit Ethernet interface, gigabit Ethernet) has been difficult to meet the needs of modern digital signal processing system, modern digital signal processing system needs a high bandwidth, good real-time, Low BER communication interface. Optical fiber communication interface has the advantages of high bandwidth, low bit error rate, simple connection mode, etc. It is especially suitable for modern digital signal processing systems. In this paper, the FPGA of XC7K325T in XILINX K7 series is used as the control core of high-speed optical fiber communication data transmission, and the SFP (small form factor pluggable) optical module interface is chosen as the type of optical fiber interface. In the data transmission protocol, Aurora protocol based on 8b/10b code is chosen to realize the data transmission technology of optical fiber communication. Finally, the technical verification of high-speed optical fiber communication data transmission is completed on Xilinx official development suite KC705. This paper is divided into five chapters: the first chapter is an introduction, mainly about the technical background of high-speed optical fiber communication data transmission, and the current research status of optical fiber communication. In addition, the research content and structure of this paper are explained in detail. The second chapter is the research of the data transmission technology which is covered by the optical fiber communication transmission system. It mainly describes the protocol, definition, optical transceiver module and the advantages of optical fiber communication. In addition, the technology of high speed serial data transmission, which is widely used in high speed system, is described in detail, including the technology of high speed serial transmission based on FPGA. Based on the detailed analysis of the underlying hard core GTX module in the high speed serial transmission technology, this paper also summarizes the high speed optical fiber communication protocol Aurora 8b/10b technology protocol in this paper. The third chapter is the hardware design of the high-speed optical fiber communication data transmission system based on FPGA. Firstly, the selection of the overall hardware scheme, technical index, core device and optical fiber communication interface module is explained. Then the hardware circuit design of each sub-module is described in detail, including fiber interface circuit, power circuit, download circuit, storage circuit, optical fiber communication clock module circuit. The global clock module circuit and FPGA minimum system module circuit design are described in detail. The fourth chapter is to explain the design of control software in optical fiber communication data transmission system, including the development environment of this subject, the overall software design framework, the brief introduction of development language, the logic design of optical fiber interface communication and FPGA logic control. The logical FPGA program of the control module is set up, and the simulation of the software control module of each module is verified. The fifth chapter is to demonstrate the development and implementation of high-speed optical fiber communication data transmission technology based on FPGA. This paper uses Xilinx official KC705 development suite as the verification platform to verify the data transmission of optical fiber communication interface. Through the analysis of the overall test results, the final test results show that the design of high-speed optical fiber communication data transmission fully meet the design requirements.
