The software error handling determines the nature of the fault and takes different action depending upon the nature of the fault. If the fault prevents the data processing system from continued reliable operation, then the element causing the fault is immediately disabled. Otherwise, the element which is the source of the fault is treated so that it does no harm to the system and causes no further faults. The element can then be completely handled during normal software status checks.

Method of handling errors in software

Hardware error processing is undertaken to analyze the source of the error and to preserve sufficient information to allow later software error processing. The hardware error processing also allows, for certain errors, complete recovery without interruption of the sequence of instruction execution.
