Hi,
Can anybody tell me what are the factors i have to consider while designing a async FIFO?
Again While desinging fifo why we code write and read pointer in gray code not as a simple counter??
IN Async FIFO u need to focus more on metastalbility.We use gray code because in case of gray code only one bit will change when pointer increase which help to synchronise the two clock domain (write and read clock).
For more information search one google u ll get good material on it.
SNUG has two papers about the async fifo which are sytle1 and sytle2
but when u read sytle2, be careful about the asyschronous reset&set signal for empty&full, i think there are some problems, which are glitches.
