sc_port zero copy?

Recommended Posts

There will only be one copy initialized: slave_port, simple_bus_slave_if will not be instantiated (which usually is even not possible as those are in the common case pure virtual classes). N just defines how many interface can be bound at most, 0 means unlimited. Internally there is a vector holding pointers to the simple_bus_slave_if , no copies. The vector will be resized as soon as you bind an interface.

Best regards
