aren't really well suited for this type of multiprocessing (i.e. only with pools of shared memories). Much better would be to take advantage of the local memories (maybe using a shared memory too along with the FSL connections).

I would say that most system aren't ready for this since it requires special startup code.

there would be anyway problems to manage the same code for both the processors... In fact, I think that it would be rather easy to "jump" to the different code for the processor rather than "branching" on the code depending on the CPU constant signal (identification). What do you think?

Having the same program for boths requires a godd startup code to setup the stack and heap pointers correctly for each processor. Having two seperate programs requires a merge of the two elf files into one elf files and also different reset handling (starting to execute a different addresses)

(thinking about CELL Architecture)...

Yes.
