摘要:

针对8核DSP TMS320C6678与外部设备进行数据通信的需求,以片上集成千兆以太网交换子系统为核心,选取芯片88E1111作为PHY设备,设计了千兆以太网通信接口的硬件电路。在嵌入式操作系统SYS/BIOS和网络开发环境NDK上,完成了以太网底层驱动和TCP/IP协议的程序设计。通过DSP与上位机进行以太网通信测试,证明了以太网接口电路硬件及软件的正确性和实用性。

关键词: TMS320C6678, 千兆以太网, SYS/BIOS, TCP IP协议

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.

Key words: TMS320C6678;gigabit Ethernet;SYS BIOS;TCP IP protocol
