A 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] As the main bus of data communication, Fiber Channel (FC) network is used in a variety of aircraft avionics systems. The state is stable and meets the advanced integrated architecture requirements of avionics systems. It has become the preferred solution for military avionics systems in the present and future. The fiber 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 / subsystem, is responsible for submitting application data to the network, or collects data from the network and submits it to the application, and also has network management. and clock synchronization function. [0003] At present, my country's Fiber Channel node card design technology is relatively weak, and there is no Fiber Channel node ca...
