摘　　要：嵌入式系统与Internet网络结合一直是国内外研究的热点,本人结合嵌入式以太网的发展现状和在研项目,提出了一种基于开源32位OR1200微处理器的嵌入式以太网网关的解决方案。系统采用软硬件协同的设计思想,在构建的OR1200平台上移植了μC/OS-Ⅱ操作系统,加入了μC/TCP-IP协议栈,添加网络设备驱动,实现了嵌入式以太网的功能。测试结果证明本系统网络通信稳定、可靠。While many people domestic and overseas are focusing on combing embedded systems with Internet, Combining the development of Embedded Internet and research project at present, thesolution of Embedded Ethernet Gateway was put forward based on the 32-bit OR1200 MPU.System use Hardware and software co-design ideas, migrate μC/ OS-Ⅱ onto the built OR1200 platform , μC/ TCP/ IP stack and device drivers were imported, and the embedded Ethernet has realized. Test results prove that network communication is stable and reliable.
