Abstract: A system and method for monitoring processors operating in lockstep to detect mismatches in pending pipelined instructions being executed by the processors. A lockstep monitor implemented in hardware is provided to detect the mismatches in the pending pipelined instructions executing on the lockstep processors and to initiate an auto-recovery operation at the processors if a mismatch is detected.
