Design of Embedded Ethernet Interface based on SEP3203

In the automatization control and other civilian equipment and industry control fields such as electric power system ,The external communication interface of many equipments are still low-speed serial interface. But there are inherent drawbacks of low-speed serial interface which're unable to monitor data concentrate, comprehensive, accurate and real-time.This thesis introduces hardware and software design methods based on Ethernet Interface in Serial Ethernet converter of microprocessor SEP3203.It can change the traditional serial communications to network communications and realize the rapid networking of serial device.
