A survey of recent prefetching techniques for processor caches
As the trends of process scaling make memory systems an even more crucial bottleneck, the
importance of latency hiding techniques such as prefetching grows further. However, naively …

Pythia: A customizable hardware prefetching framework using online reinforcement learning
Past research has proposed numerous hardware prefetching techniques, most of which rely
on exploiting one specific type of program context information (eg, program counter …

Bingo spatial data prefetcher
Applications extensively use data objects with a regular and fixed layout, which leads to the
recurrence of access patterns over memory regions. Spatial data prefetching techniques …

Efficiently prefetching complex address patterns
Prior work in hardware prefetching has focused mostly on either predicting regular streams
with uniform strides, or predicting irregular access patterns at the cost of large hardware …

Linearizing irregular memory accesses for improved correlated prefetching
This paper introduces the Irregular Stream Buffer (ISB), a prefetcher that targets irregular
sequences of temporally correlated memory references. The key idea is to use an extra level …

Spatial memory streaming
Prior research indicates that there is much spatial variation in applications' memory access
patterns. Modern memory systems, however, use small fixed-size cache blocks and as such …

DeNovo: Rethinking the memory hierarchy for disciplined parallelism
For parallelism to become tractable for mass programmers, shared-memory languages and
environments must evolve to enforce disciplined practices that ban" wild shared-memory …

Evaluation of hardware data prefetchers on server processors
Data prefetching, ie, the act of predicting an application's future memory accesses and
fetching those that are not in the on-chip caches, is a well-known and widely used approach …

Domino temporal data prefetcher
Big-data server applications frequently encounter data misses, and hence, lose significant
performance potential. One way to reduce the number of data misses or their effect is data …
