A DMI example

Let’s go with the Direct Memory Inteface (DMI) defined in TLM-2.0. DMI mechanism in roughly speaking is to pass over transactions, protocols and so on. In short, the Target sends a pointer to its memory region (o part of it) to the Initiator to allow him to that memory region directly, without using transaction. This way, we speed up the simulation, because everything is more easy.  DMI is focsed on memory type devices connected to modules that are accessing very frequently to that memory devices, like CPUs or DMAs. But the mechanism is there, and we can use it in any of our modules.
