中文摘要:

      针对商用嵌入式TCP/IP协议栈费用昂贵的情况并根据功放预失真系统网络通信特点，提出了基于SOPC技术的嵌入式以太网通信模块设计方案。实现了软核NiosⅡ处理器和实时多任务操作系统μC/OS-Ⅱ为中心的硬件平台和软件驱动的设计、多任务操作系统μC/OS-Ⅱ的移植以及嵌入式TCP/IP协议栈的设计，最终在Stratix EP2S60F1020C4开发板上通过了验证。

英文摘要:

      A design of embedded Ethernet communication module based on SOPC is presented according to the network communication characteristics of the power amplifier predistortion system (PAPS)，in view of the expensive cost of the commercial embedded TCP/IP protocol.The hardware system with the embedded NiosⅡ CPU soft IP core and the tailorable open-source kernel RTOS μC/OS-Ⅱ are utilized to implement the design of the hardware platform and software driver，the transplant of multitasking μC/OS-Ⅱ system and the design of the TCP／IP protocol stack.Finally，the embedded Ethernet communication module is verified with the Stratix EP2S60F1020C4 development board.
