Abstract

In this paper an embedded web module based on SOPC is designed to solve the problem that some intelligent instruments cannot access to the Internet at present. The design of the module was implemented at Cyclone II series chip EP2C35 based on SOPC technology. The soft-core processor Nios II and other peripheral interfaces required by the module were custom-built in SOPC Builder. The transplantation of modified UC/OS-II kernel and the light weight TCP/IP protocol LWIP was implemented in Nios II IDE. Experimental results show that, the web module works more efficiently. This design firstly adopts modified UC/OS-II kernel, which can deal with more tasks. So it is very flexible and can be applied to many occasions.
