Design of Embedded Ethernet Network Terminal Based on TCPIP Protocol Stack

The Embedded technology applications in the field of Ethernet are becoming one very important subject.This paper presents one scheme of embedded Ethernet network terminals based on TCPIP protocol stacks.The hardware institution for the interface circuit between the microprocessor S3C44B0X with ARM kernel and the Ethernet controlled chip RTL8019AS is designed.About the software,the designing idea and detailed developing process of embedded TCPIP Protocol stacks and the core transplanting of the real-time operating system μCOS-Ⅱ are introduced.This kind of embedded Ethernet network terminals has high performance price ratio.It is expected to use for home automatic devices or industrial control devices with low needs of communication speed.
