The system architecture of the Embedded Tri-mode Ethernet is introduced. In hardware design, it mainly elaborates embedded module design based on EDK and the circuit design based on Gigabit Ethernet P Y chips 88E1111-RCJ from MARVELL Co. While in software design, it mainly expounds using V DL + + for MAC timing control design and using C for Embedded module design. And the simulation and test results are given.
