Avalon MM slave/master to AXI Stream Master/Slave

(Host = master, agent = slave)

Avalon memory-mapped interfaces cannot be bridged to AXI streaming interfaces (assuming we're talking about connections in Platform Designer) or vice versa. Avalon and AXI memory-mapped interfaces can be connected to each other, but the streaming versions cannot (and you can't connect Avalon streaming to AXI streaming either).
