this is an unfortunate reading of BS marketing text.
the hammerfall series (digiXXXX and HDSP) do nothing of the sort, they
never did, they don't on any other OS, etc etc etc.
all that RME is referring to here are 2 things:
a) direct monitoring without CPU involvement
- well yeah, except that even consumer analog
cards do that
b) the card is a DMA busmaster, and so the CPU doesn't
need to be involved in transferring data to the
card, it just stuffs it into host-side RAM
- well yeah, except that almost every other
PCI card on the planet *except* RME's
earlier designs do this too. this is
really just an apology for the incredibly
stupid design of the digi96 series, which
require active participation by the host
CPU to move data to the card.
