@@@@In order to achieve efficient data communication between the embedded system and computer, this paper proposes a design of Ethernet interface based on MicroBlaze soft-core microprocessor of Xilinx FPGA and DM9000A Ethernet controller. It mainly describes the development process of MicroBlaze soft-core microprocessor and the basic working principle of DM9000A, gives the scheme of system platform hardware connection, and discusses in detail the Ethernet interface software initialization and the software implementation of data transceiver module. The experimental result shows that this system could successfully realize embedded Ethernet data communication based on FPGA.
