基于FPGA的嵌入式以太网通信

Implementation of Embedded Ethernet Communication Based on FPGA

提出了一种基于FPGA和DM9000A的嵌入式以太网通信的设计方法,阐述了硬件部分的电路组成和MicroBlaze软核处理器的一些片内外设IP核,以及简化的TCP/IP协议栈的实现方法。软件采用Standalone的运行方式,软件代码直接运行在裸CPU核上。与嵌入式操作系统相比,节约了系统资源,提高了运行速度。

Presents a design of embedded Ethernet communication based on FPGA and DM90OOA.In the hardware segment,it introduced the circuit components and MicroBlaze and some on-chip peripheral IP core.In the software segment,it mainly introduced the implementation of simplify TCP/IP protocol stack.The software used Standalone operation mode,the software code run directly on the bare CPU core.Compared with the embedded operating system,it saves system resources,increases speed.
