Abstract: The method enables an improved and faster error recognition of software errors in a processor or processor system in which programs subject information received from other programs to an error check, particularly to a plausibility check, and, given acquisition of error statuses, output a corresponding error message to the operating system. This error message contains an indication of the other program generating the faulty information and is stored in a respective error message table. The operating system thus learns of programs suspected of working in a faulty way from other programs collaborating with these programs, so that program errors can be recognized and localized significantly faster.
