  • Computer system with a cache coherent non-uniform memory access architecture using a fast tag cache to accelerate memory references
    Patent number: 5787468
    Abstract: A fast tag cache is an array to cache a limited set of identifiers specifying the residency and access rights to memory blocks and cache blocks contained in a node within a distributed memory system built using a cache coherent non-uniform memory access architecture. The purpose of the fast tag array is to ensure peak processor-memory bus throughput each node and minimize the amount of memory required to hold cache state information.
