Abstract
The Ethernet controller is designed with DSP(Digital Signal Processor) chip and NIC(Network Interface Controller)chip ENC28J60.We introduce the features of stand alone ethernet controller ENC28J60 with SPI(Serial Peripheral Interface) interface and the hardware design of external interface circuit.The embedded TCP/IP system's choice is analyzed.The process by which DSP chip controls NIC and the embedded TCP/IP protocol processing the data are discussed.The data can be processed according to network protocol,so the transmission of the data through Ethernet is realized.
