Puppeteer: A Random Forest-based Manager for Hardware Prefetchers across the Memory Hierarchy. (arXiv:2201.12027v1 [cs.AR])

Over the years, processor throughput has steadily increased. However, the
memory throughput has not increased at the same rate, which has led to the
memory wall problem in turn increasing the gap between effective and
theoretical peak processor performance. To cope with this, there has been an
abundance of work in the area of data/instruction prefetcher designs. Broadly,
prefetchers predict future data/instruction address accesses and proactively
fetch data/instructions in the memory hierarchy with the goal of lowering
data/instruction access latency. …
