A NOVE RE-READABLE SYNCHRONOUS FIFO DESIGN
Zhou Guo-xiang · Journal of Chaohu College · 2012
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.
