From what I understand MT6235 has just one ARM926EJS

DSP. This probably means that the it runs both the application and
the GSM stack on a single CPU , right ?
I read in an article about Symbian that it's able to do this because
it's a realtime OS but to my knowledge Linux is not ( hence the GSM
stack runs on a second processor in Android phones ). Now I also know
there's a realtime Linux kernel but the question is would it be
possible to run both the application and GSM stack together on the
MT6235 under Linux.
Please excuse my question if they're newbish.
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.
