Abstract

Das Verfahren zur Messung der Laufzeit einer Task in einem Echtzeitsystem mit einer Anzahl von Tasks sieht vor, dass bei Beginn der Task, deren Laufzeit bestimmt werden soll, der Zeitmesser gestartet wird, bei einer Unterbrechung der Zeitmesser gestoppt wird, der Zustand des Zeitmessers gespeichert wird und nach Beendigung der Unterbrechung der Zeitmesser erneut gestartet wird. Kern der Erfindung ist es, dass der Zeitmesser bei Beginn jeder Task gestartet werden kann und sein Zustand bei jedem Wechsel der Prioritätsebene gespeichert wird. Die erfindungsgemässe Vorrichtung zur Messung der Laufzeit weist einen Zeitmesser auf, dem ein Speicher mit einer Kapazität, die der Anzahl der Prioritätsebenen angepasst ist, zur Verfügung steht.
