Effective data prefetching requires accurate mechanisms to predict both “which” cache blocks to prefetch and “when” to prefetch them. This paper proposes the DeadBlock Predictors (DBPs), trace-based predictors that accurately identify “when” an L1 data cache block becomes evictable or “dead”. Predicting a dead block significantly enhances prefetching(More)
