阐述了一种用于暂存数据的具有可重复读取特性的同步FIFO的设计。在一般同步FIFO结构的基础上,提出数据底部指针概念。在控制逻辑的控制下,读指针可以自动返回内部逻辑产生的数据底部,或者由外部设置为数据底部指针,实现同步FIFO中存储的数据可被重复读取的功能。文中给出相关部分的Verilog代码及仿真结果。

In this paper, a new synchronous FIFO with the re-readable feature is illustrated, which can be used to store data temporarily. Based on the general synchronous FIFO, the concept of Bottom Pointer is introduced. Under the control of logic, the read pointer may gets back automatically to the Bottom Pointer generated by the internal logic, or be set to the external Bottom Pointer. Through this special mechanism, the re-readable feature can be implemented. The related Verilog code is shown as well as the corresponding simulation results.
