摘要
介绍了以DSP为核心具有以太网接口的系统的硬件电路组成和软件设计方法。对系统硬件设计进行了介绍,详细地介绍了网络控制器RTL8019AS的工作原理及DSP硬件电路设计。在DSP中实现了简化的TCP/IP协议栈,通过软件编程实现数据包的接收与发送。该系统可以将数据按照网络协议处理,实现数据的以太网传输。
This paper introduces a method of hardware constitution and software design of system containing Ethernet interface and adopting DSP as its core processor.The hardware design of system,the work principle of network controller RTL8019AS and the hardware circuit of DSP are given.The TCP/IP is achieved in DSP,and the data transmission by software program is implemented.The data can be processed according to network protocol,so the transmission of the data through Ethernet is realized.
