Cache directory look-up re-use as conflict check mechanism for speculative memory requests
Patent
·
OSTI ID:1093237
In a cache memory, energy and other efficiencies can be realized by saving a result of a cache directory lookup for sequential accesses to a same memory address. Where the cache is a point of coherence for speculative execution in a multiprocessor system, with directory lookups serving as the point of conflict detection, such saving becomes particularly advantageous.
