| 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. |
