FIFO

WHEN there is no data in fifo.......

If i do a write operation.........along with the read operation........

FIFO

how is that possible !!
reading n writing at same time ... in case if u r reading with different clock with low freq then thr is thin chance of possibility

You can implement this kind of special design, if you need it.
Normally, you can read data one clock cycle after write data has been written into the FIFO.

Re: FIFO

i think if u read a data when FIFO is empty, then u get no output.

how can u read and write at once, first try to write then read.
