I'm not really sure how you would accomplish what you think you're trying to accomplish here.

For instance for the audio you would have to retrieve the data from the database, even if database is just a buzzword of abstraction meaning a variety of long term storage the audio can't just "grab" it from the database. I'm assuming database just means "data" because getting audio from a database sounds like a terrible idea other than as a reference to where files are.

There's no "audio program" or something either, your simulator is going to get the data from somewhere and use the audio code to play it, what your chart shows is basically expecting data and a subsection of the simulator to work without the simulator actually doing it, and there being some performance difference with it, I really don't understand.

DMA transfer is not even remotely in the same category of what you're talking about because DMA transfer relies on hardware units, hardware may not be the CPU but it still has intelligent processing of data, it has the capacity to access other parts of the system and that isn't at all akin to your "audio and video units" it would always be a section of your user running code.
