1. How to overcome the convergence and Divergence in the crossover path?

2. What is the difference between Dual Port RAM Synchronizer and Asynchronous FIFO Synchronizer?

3. Why the Dual Port RAM is having less area when compared with the FIFO memory?
 

1.Convergence-> Feed a synchronizer only from a flip flop and not from combi logic.
Divergence -> Synchronize a signal only once from 1 clock domain to another. Don't generate multiple copies.

2. What is a dual port RAM synchronizer? Never heard of it before...

3. A FIFO internally has a RAM along with other logic..So RAM area should always be less...
