摘　　要：设计了以ATmega128为核心的以太网接口实现方案,描述了该系统硬件架构的设计方法。在系统上移植了C/OS-II操作系统,对TCP/IP协议栈提出了裁剪和改进方法,重点阐述了基于C/OS-II消息机制和函数调用的TCP协议的模块结构。最终给出了系统性能测试结果。A solution ofethernet interface based on the core of ATmegal28 and its architecture of hardware is illustrated. The operating system of μC/OS-Ⅱ is transplanted to the system and the improvement of TCP/IP protocol is implemented. It dwelled on the module structure of TCP protocol which based on message and function of μC/OS-Ⅱ. Finally, the test of systemic performance is presented.
