Hi, I have some problem detecting the full and empty conditions in an asynchronous FIFO design. Hope any of you can help. Assume wr_clk is slower than the rd_clk. The rd_ptr is synchronized to the wr_clk domain to generate the full flag in wr_clk (slow) domain while the wr_ptr ...

which are displayed as fifo_full and fifo_empty. The "fifo_full" means the fifo memory is full and not allowed to write data. While the "fifo_empty" indicates that there is no next valid data could be read in memory.
An empty flag can be generated by switching the read and write clock inputs and changing the look-ahead decoded internal full flag to a look-ahead decoded internal empty flag. All of these features are realized without requiring any counters, adders or decoders in the speed path of the ...
PROBLEM TO BE SOLVED: To provide constitution of a state machine for generating a full flag indicating this state when FIFO (buffer) is filled up, and generating an empty flag indicating this state when FIFO (buffer) is empty.ANDORUU ERU HOOKINZU...
This repository stores a verilog description of dual clock FIFO. A FIFO is a convenient circuit to exchange data between two clock domains. It manages the RAM addressing internally, the clock domain crossing and informs the user of the FIFO fillness with "full" and "empty" flags. ...
