Abstract

In order to achieve Ethernet data communication between DSP and peripheral devices,a mde of DSP Ethernet interface based on network control chip DM9000A was adopted. Taking TMS320F28335 DSP of TI and network control chip DM9000A as hardware platform,DM9000A internal registers is controlled with DSP bus to complete DM9000A initialization and the underlying Ethernet data transceiving. The Ethernet data communication functions suitable for DSP devices were achieved by simplifying TCP/IP protocol,including IP,ARP,ICMP,UDP,TCP protocols,etc.
