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 …

Hardware prefetching is an important feature of modern high-performance processors.
When the application working set is too large to fit in on-chip caches, disabling hardware pre …

Designing prefetchers to maximize system performance often requires a delicate balance
between coverage and accuracy. Achieving both high coverage and accuracy is particularly …

This paper presents Voyager, a novel neural network for data prefetching. Unlike previous
neural models for prefetching, which are limited to learning delta correlations, our model can …

High performance processors employ hardware data prefetching to reduce the negative
performance impact of large main memory latencies. While prefetching improves …

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 …

Due to limits in technology scaling, energy efficiency of logic devices is decreasing in
successive generations. To provide continued performance improvements without …

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 …

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 …

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 …
