Design and implementation of 10 gigabit protocol conversion system based on FPGA
10 gigabit communication technology has become another research hotspot in the field of satellite communications, and it is especially important to provide high-speed and reliable 10 gigabit data sources for on-board devices. The system adopts the newly launched K7 series Field Programmable Gate Array(FPGA) from Xilinx, and realizes the 10 gigabit protocol conversion function by using its GTX interface module and 10 gigabit MAC module. The state machine design method realizes the mutual conversion between the Ethernet protocol frame and the dedicated link protocol frame. The test results show that the system achieves a conversion bandwidth of 10 Gbit/s per channel, and the total bandwidth reaches 40 Gbit/s, which can meet the testing requirements of satellite equipment.
