| 摘 要： | 针对传统嵌入式系统中网络传输速度较慢的现状,采用ARM9处理器(S3C2440)与高速以太网芯片W5300相结合的方案,开发了W5300在Linux下的驱动程序,并组建了嵌入式高速传输系统。重点对W5300驱动程序进行了深入的分析,实现了该网卡在Linux环境下的移植,并通过FTP实验进行了网络性能对比测试。实验结果表明该方案能达到2.8 MB/s的传输速率,具有较好的实际应用价值。

| Abstract: | Different from traditional embedded systems in which the transmission speed is relatively low,high speed transmission embedded systems are constructed with the integration of high speed Ethernet chip W5300 and ARM9 MCP (S3C2440).In this work,W5300 driver is developed under Linux.W5300 driver is analyzed in depth for the purpose of the transplantation of Ethernet network card into Linux OS,and contrastive network performance test of FTP experiment is implemented.The experimental results verify that this solution is able to provide 2.8 MB/s transmission speed,and is practical for industrial applications. |
