I'm not sure what assembly has to do with it, but you do realize that
the "central microprocessor" will become the bottleneck, throttling
down the performance of the entire system, right?

Note that once you get above four processor, you reach the point of
diminishing returns in standard shared memory multiprocessor systems.
You need special busses to get decent performance above that point.
Also, if you're trying to improve the performance of a single
application via multithreading, it's real hard to get good performance
gains except for specialized algorithms once you get above 4-16
threads.
