Design and implementation of network interface module based on FT2000_4

Gigabit Ethernet switching system is very important in aerospace, sonar signal processing and other field. Under the condition of keeping the original device architecture unchanged as far as possible, in order to make the device more convenient for high–speed data exchange and communication with other peripherals, and consider the economic cost, a small Gigabit Ethernet switching system is preferable solution. This paper proposed a design and implementation of network interface based on FT2000_4. FT2000_4 is a domestic independent research and development CPU chip, it combined with other chips such as DDR4 SDRAM, bridge chip, SSD, WX1860 NIC chip, Gigabit Ethernet switch chip CS8367 and so on, the module adopted LRM structure and migrated with Kylin operating system. Related drivers and applications are developed based on this operating system. The hardware and software performance of this module was stable and reliable after system test and joint verification.
