I don't think there are many interchangeable parts in DSP world. Opamps and
other analog stuff is usually pin compatible, but I haven't seen any cross
manufacturer pin compatible converter parts. I think using DSP processors is
closest when programmed at C level. We can't simply replace DSP chips with
other manufacturers chips, but we could possibly make the code cross-DSP
compatible.
Hmm, unless we create some daughter card architecture to isolate the
pincompatibility issues to separate small modules. This is more difficult to
design well, but I think it would be great to have completely modular
system.
