| Abstract: | For the demand of data communications between TMS320C6678 and external devices,a gigabit Ethernet communication interface hardware circuit is designed with on-chip Gigabit Ethernet switching subsystem as the core and 88E1111 as the PHY device.Under embedded operating system SYS/BIOS and network development environment NDK,the Ethernet underlying driver programming and TCP/IP protocol is completed.The communication tests between DSP and PC verify the correctness and practicability of the Ethernet interface circuit hardware and software. |
