UART module Verilog codes and guidance

用verilog实现dsp与Fpga接口的同步设计，其功能包括读写操作及四个功能模块，采用两个fifo实现不同时钟域的地址与数据的转换，在quartus ii11.0环境下运行，运行此程序之前需运行将调用fifo。(Dsp using verilog achieve synchronization with Fpga interface design, its features include read and write operations and four functional modules, using two different clock domains to achieve fifo address and data conversion in quartus ii11.0 environment to run, run this program required before running calls fifo.)

说明：  模糊控制器verilog程序，模糊控制器最简单的实现方法是将一系列模糊控制规则离线转化为一个查询表（又称为控制表）。这种模糊控制其结构简单，使用方便，是最基本的一种形式。(Verilog program of fuzzy controller)
