Abstract

Silent Data Corruption (SDC) in processors can lead to various application-level issues, such as incorrect calculations and even data loss. Since traditional techniques are not effective in detecting processor SDCs, it is very hard to address problems caused by SDCs. For the same reason, knowledge about SDCs in the wild is limited.
