本文阐述了UART异步串行通信原理,FPGA基本结构和开发流程以及发展方向,介绍了FPGA开发软件QuartusII和仿真软件Modelsim。完成UART控制器的Verilog HDL程序,通过Modelsim仿真软件得到正确仿真波形。FPGA是英文Field Programmable Gate Array的缩写,即现场可编程门阵列,它是在PAL、GAL、EPLD等可编程器件的基础上进一步发展的产物。它是作为专用集成电路(ASIC)领域中的一种半定制电路而出现的,既解决了定制电路的不足,又克服了原有可编程器件门电路数有限的缺点。UART即Universal Asynchronous Receiver Transmitter通用异步收发器,是广泛使用的串行数据传输协议。异步串行通信要求的传输线少,可靠性高,传输距离远,被广泛应用于微机和外设的数据交换。在计算机中,UART相连于产生兼容RS232规范信号的电路。RS232标准定义逻辑“1”信号相对于地为3到25伏,而逻辑“0”相对于地为-3到-25伏。所以,当一个微控制器中的UART相连于PC时,它需要一个RS232驱动器来转换电平。用FPGA实现UART功能,可以减小系统的面积,降低系统的功耗,提高设计的稳定性,也充分利用了FPGA的剩余资源。
