基于DSP的以太网通信接口设计

Design of Ethernet communication Interface Based on DSP

介绍了以DSP为核心,具有以太网接口的嵌入式系统硬件电路组成和软件设计方法。详细地介绍了网络控制器RTL8019A的工作原理及DSP硬件电路设计。解析了嵌入式TCP/IP协议在DSP硬件上的移植,在此协议栈的基础上,完成了上层协议的编写和实现。

This article explain the hardware circuits composition and software design method of the system, this system is a embedded system which has Ethernet interface and DSP as its core .This article also explains in detail the working principle and DSP hardware circuit design of the network controller RTLS019. We provide embedded TCP/IP protocol transplantation on DSP hardware. Based on this protocol stack , we complete upper protocol.
