Actually, using multiple simple processors working together would be much more effective (effort- and maybe overall cost-wise) for most embedded applications. It is basically more efficient to work in small and numerous units rather than a single large unit, a principle which is observed often in nature.

That is TRUE multi-tasking (parallelism), rather than time-shared multi-tasking. Buses like I2C make it very easy to implement such systems.

I am not sure what DPM means in this context though... could you explain?
