采用Xilinx的ISE、EDK设计工具,利用Virtex-5 LXT芯片实现嵌入式三态以太网。主要介绍了嵌入式以太网的系统结构,在硬件设计方面,详细阐述了基于EDK的嵌入式模块设计以及MARVELL的88E1111-RCJ物理层接口芯片的外围电路设计;在软件方面,详细阐述了采用VHDL进行MAC控制器的时序控制设计和采用C++进行MicroBlaze的嵌入式模块的设计,最后给出了仿真结果。 Using Xilinx ISE, EDK design tools, the use of Virtex-5 LXT chip embedded three-state Ethernet. Mainly introduces the system structure of embedded Ethernet. In terms of hardware design, the design of embedded module based on EDK and the peripheral circuit design of MAREELL’s 88E1111-RCJ physical layer interface chip are described in detail. In terms of software, MAC controller timing control design and the use of C + + MicroBlaze embedded module design, and finally gives the simulation results.
