Abstract

Abstract

Network terminal (NT) is the data transmission and processing terminal in optical fiber databus, and is also an important part of that. A kind of NT, which intergrated multiple interfaces such as universal asynchronous receiver and transmitter (UART), controller area network (CAN), ethernet and peripheral component interconnect express (PCIE) was introduced. The hardware foundation of this kind of NT was field programmable gate array (FPGA). Through the design of the corresponding intellectual property modules (IP core) of each interface and the design of data-format conversion logic module of different interfaces based on the FPGA platform, the NT design that met the requirements of optical fiber databus was completed. The NT designed in this method could deal with data in different interfaces such as UART, CAN, ethernet and PCIE on optical fiber databus in low time delay. Finally, through the comparison with similar databus products and standards at home and abroad, the results show that the optical fiber databus composed of this kind of NT can effectively solve the problem of data transmission between different types of interfaces.
