CPU & Core Duo Technical Question

[kdum8]

Not sure where to post this but...

Could someone explain what exactly is the physical difference between a core duo cpu and a one core processor? I know that a core duo has two microprocessors instead of one single processor and so allows system processes to run in a separate processor, but how do the two processors communicate with each other? Is one the main processor which decides how to break up tasks and deligate? Also with the upcoming eight core cpu's how on earth does such a chip manage to distribute tasks efficiently, isn't this all a kind of parallel processing?

OK, so maybe I posted this in the wrong forum....

Where should a post like this ideally go?

but how do the two processors communicate with each other?

Shared onboard cache or via front side bus.

Operating system and multi-threaded applications.
