    The Avalon memory mapped interface allows a master to access a component using random addressing. It uses both address and data vectors and can read/write any address on the slave.

    The Avalon stream interface is a sequential set of data vectors sent one after the other. It is very efficient when you have a continuous flow of data to send from one source to a destination, but doesn't allow random access.
