使用lwip的spartan 3a Dsp 1800a中UDP的最大数据速率

我会说最大数据速率主要/完全取决于您的设计。

I'd say that the maximum data rate depends mostly/entirely on your design.

我没有S3A1800ADSP板的数据，但为Avnet Spartan-6 LX16评估板（http://www.em.avnet.com/spartan6lx16-evl）构建的类似MicroBlaze + Ethernetlite系统表明~76Mbps UDP
在客户端模式下使用iperf可以实现吞吐量（向数据包发送数据包）：
C：> iperf.exe -c 192.168.1.105 -u -b 100M -l 56k
--------------------------------------------------
----------客户端连接到192.168.1.105，UDP端口5001发送57344字节datagramsUDP缓冲区大小：8.00 KByte（默认值）-------------------
----------------------------------------- [1832] local 192.168.1.50 port 4175
连接192.168.1.105端口5001 [ID]间隔传输带宽[1832] 0.0-10.0秒90.6 MBytes 75.9 Mbits / sec [1832]警告：10次尝试后没有收到最后一个数据报的确认。[1832]
发送了1657个数据报
查看Avnet DRC上的S6LX16评估板Ethernetlite网络性能设计，了解如何为您自己构建和配置此设计和教程。
除了演示之外，UDP吞吐量高度依赖于网络拥塞以及MicroBlaze处理器系统的繁忙程度。

I don't have data for the S3A1800ADSP board, but a similar MicroBlaze + Ethernetlite system built for the Avnet Spartan-6 LX16 Eval Board (http://www.em.avnet.com/spartan6lx16-evl) indicates that ~76Mbps UDP throughput is possible using iperf in client mode (sending packets to the board): 
 
C:>iperf.exe -c 192.168.1.105 -u -b 100M -l 56k
 
------------------------------------------------------------
Client connecting to 192.168.1.105, UDP port 5001

Demonstration aside, UDP throughput is highly dependent on network congestion and how busy your MicroBlaze processor system is.  Standard disclaimers apply.  Your mileage may vary.
