WebJust like the converter to a FWFT FIFO, there is an instantiation of a regular FIFO, orig_fifo. The logic in the reg_fifo module attempts to keep @fifo_dout's value valid by reading a word from orig_fifo when @fifo_dout doesn't contain a valid value. But in addition to that, there's a second register, which is called @middle_dout.

If the head is readily available, it is known as a “look-ahead fifo” in Intel IP literature and an “FWFT (first-word-fall-through) fifo” in Xilinx IP literature. The look-ahead fifo is easier to use and better for a beginner.
