基于S3C2410A的嵌入式网络通信系统设计与实现*

针对嵌入式系统在网络通信中的应用需求，设计并实现了一种基于ARM9微处理器S3C2410A的嵌入式网络通信系统，给出了系统的电路设计方法。重点介绍了系统在ARM-Linux嵌入式操作系统环境下，实现socket通信的Qt/Embedded应用程序的设计方法，并给出了部分源代码。采用此方案设计的嵌入式网络通信系统成本低、功耗小、实时性好。实验结果表明此系统工作稳定、性能高。

Design and implementation of embedded communication system based on S3C2410A

Aiming at the application requirement of embedded system in network communication, this paper put forward a design and implementation of an embedded network communication system based on S3C2410A ARM9 microprocessor. It gave part of the circuit diagram of this system. Furthermore, the design of Qt/Embedded program in the ARM-Linux operation system environment realizing socket communication, along with some code. The system was real-time, and had advantages of low cost and low power consumption. Experiments demonstrate that it is high efficient and stable.
