Description: FIFO电路(first in，first out)，内部藏有１６ｂｉｔ×１６ｗｏｒｄ的Dual port RAM，依次读出已经写入的数据。因为不存在Address输入，所以请自行设计内藏的读写指针。由FIFO电路输出的EF信号(表示RAM内部的数据为空)和FF信号(表示RAM内部的数据为满)来表示RAM内部的状态，并且控制FIFO的输入信号WEN(写使能)和REN(读使能)。以及为了更好得控制FIFO电路，AEF(表示RAM内部的数据即将空)信号也同时输出。

Description: Synthesizable FIFO Model
This example describes a synthesizable implementation of a FIFO. The FIFO depth and FIFO width in bits can be modified by simply changing the value of two parameters, `FWIDTH and `FDEPTH. For this example, the FIFO depth is 4 and the FIFO width is 32 bits.

Description: FIFO（先进先出队列）通常用于数据的缓存和用于容纳异步信号的频率或相位的差异。本FIFO的实现是利用
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. The realization of this FIFO is to use dual-port RAM and to read and write address generator module achieved. FIFO interface signals, including asynchronous write clock (wr_clk) and read clock (rd_clk), and write effectively write clock synchronization (wren) and write data (wr_data), clock synchronization and time effective reading (rden) and read data (rd_data) in order to realize the right to read and write and to avoid FIFO overflow or the underflow, is given with the time clock and write clock synchronization FIFO respectively empty signs (empty) and full logo (full) to prohibit the read and write operations.

Description: 设计实现4bit FIFO, 数据深度为8， 产生满， 空状态标志-The diagram of FIFO is shown in figure 1. The FIFO consists of two component: FIFO control
logic and RAM. The control logic generates the address (ADD) and write enable (WE) to the
RAM so that the first data word written into the RAM is also the first data word retrieved
from the RAM. As shown in the Figure 1, the RAM is implemented to operate as a FIFO. The
RAM is assumed to have separate data inputs and outputs, an N-bit address bus (ADD) and an
active high write enable (WE). The inputs to FIFO/Stack include PUSH, POP, INIT (all
active high) in addition to the rising edge triggered CLK input. The FIFO logic will not only
supply the address and write enable to the RAM, but will also supply active high flags for
FULL, EMPTY, NOPOP, and NOPUSH conditions.
