So each processor will have its own I/O ports so what will need to happen is that those IO ports are multiplexed over shared devices and arbitration will be necessary.
thanks for reply.
I understood that ports from all processors will be multiplexed over one device .
if so, what if there are two processors need to communicate with same device?
well, if there is a priority ,that is meaning that one of those processors must wait.
or you may mean that all ports from one processor will be multiplexed over shared device . if so , I don't understand what are you meaning .
may because my native language isn't english, so I find some difficulty to understand.
please, i need a more clarifying , i do appreciate your help.
thanks in advance
