WebMar 30, 2024 · Normally you want to continuously enqueue/dequeue data to/from a FIFO every clock cycle. Suppose you keep write signal high for say 2 clock cycles, you have to get 2 synchronized pulses or a two-cycle long pulse at the read-clock domain, which will then update the pointers and the FIFO works flawlessly. WebWhen you send a single-bit signal from one clock domain to another clock domain (asynchronous), you SHOULD synchronise it to the destination clock domain to avoid metastability. For this purpose, We have to use flip-flop synchronisers. Traditional way is to use 2-flop synchronisers. cheap holiday cottages uk dog friendly
