WebIn the FWFT mode, the first word you write to the FIFO falls through to the output and is available at the output signal Out. In the figure, though read-en becomes 1 at time step 50, the FIFO read the first word dout at time step 15. You can use this capability to look ahead and see the first word that has been written to the FIFO. WebFor a FWFT FIFO once the first word is written into an empty FIFO, it should immediately appear on the "data_out" bus. No, this assumption is wrong. FWFT FIFO just mean that in empty FIFO data will appear on the output without explicit read request. It is nowhere said, that this should happen immediately. Ok.
