Clock domain crossing … 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 …

WebJul 2, 2024 · AE and AF flags can be designed into the FIFO chip or ASIC/PLD IP, otherwise extra logic circuitry can be added around the FIFO to do it. For bursts: if the FIFO write data or read data is to be moved by burst transfer of blocks, such as across a bus in data packets, then the AE/AF thresholds can be set for when there is sufficient write space ... WebAug 5, 2024 · I think asynchronous FIFO actually internally uses gray code counter to pass the write/read address pointer across the two clock domains. You will have metastability issue if more than 1 bit is toggled in one clock domain, but no all the bits are captured by the other clock domain. One 1 bit can toggle in a gray code counter and the value stays ... how to stop kidneys from leaking proteinWebJul 6, 2024 · For a synchronous FIFO, both AW+1 bit pointers are generated on the same clock, so there isn’t an immediately apparent problem.
