I agree with the first sentence. But can you really
extract a part of a complex C function and put it into
the hardware and SystemC generates the software drivers
you need from the rest?

No? Do I have to rewrite the code each time I want to
try another split - until I am satisfied or f*#!$*ed?
(sorry! :-)

What I'd like to have is the faster simulation speed. But
it's still to slow to simulate the complete software too.
