Effectiveness of a data prefetch mechanism lies in the exploration of regular access patterns found in the memory reference address sequence.
Increasing hardware data prefetching performance using the second-level cache. Techniques to reduce or tolerate large memory latencies are critical for ...
Previous research shows that selective prefetch schemes are effective for linearly accessed memory references, including instructions and data array accesses ...
We propose IPCP in two flavors: (i) an L1 spatial data prefetcher that classifies instruction pointers at the L1 cache level, and issues prefetch requests based ...
Bibliographic details on Hardware-driven Prefetching for Pointer Data References.
As it can be seen, the Hardware Based Pointer Data Prefetcher scheme (similar to Dependence Based Prefetching) mainly relies on the ability to find the “load”.
Data prefetching has been proposed as a technique for hiding the access latency of data referencing patterns that defeat caching strategies. Rather than waiting ...
Nov 26, 2020 · -- Not easy to do for pointer-based data structures. 31 ... Record the distance between the memory addresses referenced ... Hardware uses hints to ...
Mar 2, 2013 · Now, about your main question that whether the processor can follow random pointers around and bring the data into cache before they are needed.
