Abstract
This paper describes the design and implementation of NIC driver and simple IP for an embedded OS in technical details, including the key techniques of designing NIC driver, ether net interface, ARP, IP and ICMP routines. The network routines are implemented for the ARM based multi-process micro-kernel embedded operating system developed by the author of this paper on Linux platform with GNU tool chain. A shell command, ping, is designed to show the effect of network performance. Based on the NIC driver, UDP, TCP and socket routines can be designed further. This multi-process micro-kernel embedded operating system with network capabilities is suitable and helpful for both embedded operating system research and related curriculum teaching.
