说明：  基于FPGA的串行通信UART控制器，采用VHDL语言编写，包含多个子模块。 在ISE或FPGA的其它开发环境下新建一个工程，然后将文档中的各个模块程序添加进去，即可运行仿真。源程序已经过本人的仿真验证。
(FPGA-based UART serial communication controller, using VHDL language, includes a number of sub-module. ISE FPGA or in the other developing a new environment, then documentation of the various modules of procedures added to it, will be running simulation. I have been the source of the simulation.)
