If I have 2 processors , maybe configuring as dual-port mode is better because I can connect them to each processor.

However, if I have more than 2 processors and I want to have a common shared memory, I think dual-port mode is not necessary at all and I should connect all of the processors to the common slave of the memory and use mutex to coordinate the access.Right?

:D;)
