Implementation of Ethernet Communication Interface Based on DM642

Hongxia Bie

Abstract

The Ethernet communication software and hardware based on TI digital media DSP chip DM642 were implemented. The hardware was based on EMAC/MDIO modules integrated on DM642 and the network chip Intel LXT971 PHY.Incorperating with DSP/BIOS and the TI Network developing kit (NDK),the communication software,including hardware drivers and the TCP/IP protocal stack were implemented to transfer the video stream via the Ethernet port.
