双口RAM 和读写地址产生模块来实现的.FIFO的接口信号包括异步的写时钟(wr_clk)和读时钟(rd_clk)、
与写时钟同步的写有效(wren)和写数据(wr_data) 、与读时钟同步的读有效(rden)和读数据(rd_data)
为了实现正确的读写和避免FIFO的上溢或下溢,给出与读时钟和写时钟分别同步的FIFO的空标志(empty)和
满标志(full)以禁止读写操作。-FIFO (FIFO queue) is usually used for data caching and asynchronous signal used to accommodate the frequency or phase differences.
