A new technical paper titled "Knock-Knock: Black-Box, Platform-Agnostic DRAM Address-Mapping Reverse Engineering" was published by researchers at Georgia Tech, ESILV, CentraleSupelec, Inria, CNRS, IRISA.
Abstract
"Modern Systems-on-Chip (SoCs) employ undocumented linear address-scrambling functions to obfuscate DRAM addressing, which complicates DRAM-aware performance optimizations and hind...
