Abstract

An Ethernet controller was designed with DSP chip and network interface controller ( NIC) chip ENC28J60. The features of stand-alone Ethernetcontroller ENC28J60 with SPI interface and the hardware design of its external interface circuit were demonstrated. The criterion for selection of embedded TCP/IP protocols was dis- cussed. The flowchart of control procedure of DSP chip over NIC and the TCP/IP protocol processing data package was also presented. The system can process the data according to network protocol so as to realize the transmission of the data through Ethernet.
