Design of Embedded UDP Protocol based on Foreground/Background System
This paper presents an implementation of high-reliable network card driver used in the 8-bit mcu,which enables the mcu with low performance to drive RTL8019 always correctly even in a high-load network.The method for designing a simplified communication protocol stack which includes UDP,IP,ARP and ICMP is introduced,as well as the program structure with the ability to let the embedded equipment run a long-time consumed background program without the support of a operating system by running the whole communication stack related code in the interrupt foreground program.At last this udp protocol is used in the OSD equipment in order to realize parallel control by arbitrary number of computers.
