基于DSP的网络接口电路设计

Design of Network Interface Circuit Based on DSP

DSP体积小、成本低、易于产品化、可靠性高、易扩展、能方便地实现多机分布式并行处理,所以在航空航天、工业控制、科学研究等方面获得了越来越多的应用。以DSP为核心的复杂计算和控制的嵌入式系统设计思路逐步成为电子设备工程师的首选。因此基于DSP和网卡设计了一个网络传输系统,给出了系统整体电路设计和相应的软件程序。经实验表明,该系统能成功地发射和接收信号。

There are some advantages about DSP,its bulk is small, cost is low,and it could be used in distributed parallel processing for more machines. So DSP is wildly used in aviation, industry control and science research. Electronic engineers more and more use DSP as core for complex calculating. So we design a net transmission system based on DSP and network card. We present the whole circuit design and corresponding software. As we test, this system could transmit and incept signals successfully.
