Under Linux probably not, under RT Linux maybe. Depends on the amount
of work done by DSP, CPU load by applications etc... Nothing prevents
you to implement stack and applications handling on the single CPU
except performance limitations (but you should have in mind memory
isolation, security issues, etc).

As a matter of fact, what becomes more and more attractive now days
are L4 hypervisors, which could separate BB and APP system in the
separate containers, running on the same CPU.
