ORAP: Optimized Row Access Prefetching for Rowhammer-mitigated Memory
Maccoy Merrell, Daniel Puckett, Gino Chacon +3
Rowhammer is a well-studied DRAM phenomenon wherein multiple activations to a given row can cause bit flips in adjacent rows. Many mitigation techniques have been introduced to add…
SPPAM: Signature Pattern Prediction and Access-Map Prefetcher
Maccoy Merrell, Lei Wang, Stavros Kalafatis +1
The discrepancy between processor speed and memory system performance continues to limit the performance of many workloads. To address the issue, one effective and well studied tec…
Correct Wrong Path
Bhargav Reddy Godala, Sankara Prasad Ramesh, Krishnam Tibrewala +7
Modern OOO CPUs have very deep pipelines with large branch misprediction recovery penalties. Speculatively executed instructions on the wrong path can significantly change cache st…
Exposing Shadow Branches
Chrysanthos Pepi, Bhargav Reddy Godala, Krishnam Tibrewala +5
Modern processors implement a decoupled front-end in the form of Fetch Directed Instruction Prefetching (FDIP) to avoid front-end stalls. FDIP is driven by the Branch Prediction Un…
