Claim 4:
5. The method of claim 1, further comprising:
observing, by an output lockstep monitor of the monitoring circuitry, memory accesses requested by the master processor and the checker processor;
comparing, by the output lockstep monitor, corresponding requested memory accesses of the master processor and the checker processor; and
when the corresponding requested memory accesses differ:
triggering, by the output lockstep monitor, the master tracer to output stored master trace data recorded from the output of the master processor;
triggering, by the output lockstep monitor, the checker tracer to output stored checker trace data recorded from the output of the checker processor; and
triggering, by the output lockstep monitor, the internal lockstep monitor to output observed states of the master processor and checker processor.
