Abstract

In this paper, a design and implementation scheme of a reduced data link layer for embedded web server is proposed based on ARM7 that uses RISC technology and RTL-8019 NIC (network interface controller) hardware platform. The design aims at the characteristics that the embedded system only has limited resources and reduced any unnecessary operation process. The logic structure, operation principle and DMA controller data sending and receiving principles of RTL-8019 NIC and IP packet encapsulation course have been explained in detail. The registers programming process for realizing NIC initialization, operation of local/remote DMA controller and Ethernet frame sending and receiving have been deeply discussed, which provides a completed implementation scheme of data link layer construction for embedded web server.
