ABSTRACT:
A detection and recovery mechanism is herein disclosed for soft errors corrupting TLB data. The mechanism works with a hardware page walker (HPW) and instruction steering control mechanisms in a processor to provide soft error recovery in the TLB arrays and latches. Through use of the disclosed detection and recovery mechanism, efficient and robust protection from silent data corruption is provided without requiring more expensive built-in redundancy.
