Abstract: With respect to industrialization of the original embedded microprocessor designed by Tongji University, this paper proposes an engineering method to integrate the microprocessor with the opensource Ethernet controller IP of OPENCORES organization. This method describes how to build the hardware/software interface between the microprocessor and the Ethernet controller IP, testing environment and testing vector. Hardware architecture and critical path analysis are also introduced. The method is proved out by logic simulation and FPGA emulation.

Key words: SoC, Ethernet controller, integration method
