Optical fiber channel node card

Abstract

The invention discloses an optical fiber channel node card and relates to the technical field of information transmission. The optical fiber channel node card comprises an FPGA used for finishing FC MAC and FC frame transceiving control, FC-AE-ASM protocol processing and host interface work, an FPGA CFG Flash used for storing a file of the FPGA, a communication configuration flash used for storing a communication configuration file, a JTAG interface positioned on the edge of a board and used for FPGA debugging and FPGA Image updating, a clock oscillator, a reset chip that monitors a system power-on state and provides a system reset signal, a CONN interface that provides all input and output signals, and a control module comprising an FC protocol processing part and a PCIe host interface, wherein the FPGA CFG Flash, the communication configuration flash, the JTAG interface, the clock oscillator and the CONN interface are all connected with the FPGA. The invention has the beneficial effects that the optical fiber channel node card has the characteristics of small volume and low power consumption, is low in hardware configuration amount, reduced in total power consumption, more stable in performance and relatively light in weight, and meets airborne requirements.

Description

Technical field [0001] The invention relates to the technical field of information transmission, in particular to a fiber channel node card. Background technique [0002] Fibre Channel (FC) network as the main data communication bus is applied to a variety of aircraft avionics systems. It is stable and meets the requirements of advanced integrated architecture of avionics systems. It has become the first choice for military avionics system buses now and in the future. The Fibre Channel node card plays a core management role in the entire FC network. As an interface device, it provides a communication interface for the module / sub-system. It is responsible for submitting application data to the network, or receiving data from the network and submitting it to the application. It also has network management The function of synchronization with the clock. [0003] At present, my country's fiber channel node card design technology is relatively weak, and there is no fiber channel node c...
