摘　　要：设计了一种基于NiosⅡ的UART系统,采用软硬件协作设计的思想调用了UART核并通过编译相关软件驱动的方式实现RS232协议的通信。首先介绍了UART的协议原理,然后描述了基本的硬件构造和软件编程方法。编译仿真无误后下载到芯片通过串口调试软件进行了调试验证。One kind of UART system is designed which based on Nios II .It realizes the RS232 agreement correspondence in the way of used the software and hardware cooperation design thought to transfer the UART nucleus and translated the related software actuations. First introduced the UART agreement principle, then described the basic hardware structure and the software programming method. After it has unmistakable in translated simulation, we downloaded it into the chip and confirmed it through the serial port debugging software.
