Honored ContributorIt depends on the kind of data that you want to transfer. Avalon ST are well adapted for transfer of data that comes as a stream of elements that are always the same (such as a stream of bytes, or of words). A stream only goes from one source to a destination, but you can do more complex connections using channels and multi/demultiplexers.
In a lot of systems it makes sense to use ST for data transfer and MM for control, but to give you more advice we would need more information on your system and what you need to achieve.
