What are the major issues related with multiprocessor caches and how might you resolve them?

Verified

Issue: Data coherency or Cache coherency. The problem is all the processors cache must have precisely the same shared data (as coherent data). As well as there are races possible with multiprocessors.

Possible solution: employ one central cache controller that will get all the read or write requests from all the processors and peripherals therefore it can ensure there are no races and cache coherency is maintained.
