asynchronous fifo vhdl

Hi friends,
I want to implement an asynchronous FIFO myself in VHDL, but I do not know how to generate the empty and full flag in that I don't know how to compare the write pointer with the read pointer with different clock domain.

I heard that using gray code could meet the command,but How?

Welcome anybody familiar with it to discuss with me about it!
