FIFO depth calculation

[BlackOps]

to calculate the depth of asynchronous fifo

sp3 thanks for the attached paper, i read it, but i still have questions...

please take a look at Case 2 and Case 3 inside your paper...

in Case2 at the end there is sentence:
Now divide with highest frequency time period = 160/10ns=16

and in Case3 there is following sentence:
Now Divide by the lowest frequency time period = 600/400 = 1.5 = 2

in both cases writing speed is more than reading speed... why in Case2 you divide with HIGHEST frequency time period, and in Case3 you divide with LOWEST frequency time period?

thanks!
