WebStep 3: Ram-based FIFO. So in the above step, we saw a synchronous FIFO based on registers. This time, we take a look at RAM-based FIFO. This FIFO implements its data array on RAM instead of registers. This is suitable for implementing large FIFO buffers on hardware; especially on FPGAs, where abundant block RAMs are available. WebJun 29, 2024 · Asynchronous FIFO : Asynchronous FIFO is needed whenever we want to transfer data between design blocks that are in different clock domains. The difference in clock domains makes writing and reading the FIFO tricky. If appropriate precautions are not taken then we could end up in a scenario where write into FIFO has not yet finished and …
