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…

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…
