Translation-lookaside buffer consistency

Nine solutions to the cache consistency problem for shared-memory multiprocessors with multiple translation-lookaside buffers (TLBs) are described. A TLB's function is defined, and it is shown how TLB inconsistency arises in uniprocessor and multiprocessor architectures. The problem of TLB consistency is solved in a uniprocessor and in multiprocessors with a shared bus, virtual-address caches, and hardware cache consistency. Solutions that can be implemented in multiprocessors with more general interconnection networks and without hardware cache consistency are presented.<
