=== Collaborative prefetching ===
Computer applications generate a variety of access patterns. The processor and memory subsystem architectures used to execute these applications further disambiguate the memory access patterns they generate. Hence, the effectiveness and efficiency of prefetching schemes often depend the application and the architectures used to execute them.<ref>{{Cite journal |last1=Kim |first1=Jinchun |last2=Teran |first2=Elvira |last3=Gratz |first3=Paul V. |last4=Jiménez |first4=Daniel A. |last5=Pugsley |first5=Seth H. |last6=Wilkerson |first6=Chris |date=2017-05-12 |title=Kill the Program Counter: Reconstructing Program Behavior in the Processor Cache Hierarchy |url=https://dl.acm.org/doi/10.1145/3093336.3037701 |journal=ACM SIGPLAN Notices |language=en |volume=52 |issue=4 |pages=737–749 |doi=10.1145/3093336.3037701 |issn=0362-1340|doi-access=free }}</ref> Recent research<ref>{{Cite conference |last1=Kondguli |first1=Sushant |last2=Huang |first2=Michael |date=2018-06-02 |title=Division of labor: a more effective approach to prefetching |url=https://doi.org/10.1109/ISCA.2018.00018 |book-title=Proceedings of the 45th Annual International Symposium on Computer Architecture |conference=ISCA '18 |___location=Los Angeles, California |publisher=IEEE Press |pages=83–95 |doi=10.1109/ISCA.2018.00018 |isbn=978-1-5386-5984-7|s2cid=50777324 }}</ref><ref>{{Cite conference |last1=Pakalapati |first1=Samuel |last2=Panda |first2=Biswabandan |date=May 2020 |title=Bouquet of Instruction Pointers: Instruction Pointer Classifier-based Spatial Hardware Prefetching |url=https://ieeexplore.ieee.org/document/9138971 |conference=2020 ACM/IEEE 47th Annual International Symposium on Computer Architecture (ISCA) |pages=118–131 |doi=10.1109/ISCA45697.2020.00021|isbn=978-1-7281-4661-4 |s2cid=218683672 }}</ref> has focussed on building collaborative mechanisms to synergistically use multiple prefetching schemes for better prefetching coverage and accuracy.
