Abstract

The invention relates to a system monitoring unit, which monitors a control device comprising a microprocessor by means of: a peripheral monitoring unit, which monitors the access to individual peripheral devices of the microprocessor, preventing and reporting general protection faults; a general protection management unit, which classifies reported general protection faults and stores and issues said faults with additional information; an operating mode monitoring unit, which switches the microprocessor to a supervisor mode if general protection faults are reported; a memory access monitoring unit and a runtime monitoring unit.
