Zusammenfassung

Neu eingeführte Funktionen in der Automobilindustrie, wie zum Beispiel das autonome Fahren, erfordern den Einsatz von performanten Mehrkernprozessoren sowie von komplexen (POSIXkompatiblen) Betriebssystemen. Im Rahmen des branchenspezifischen Preisdrucks kommt es zudem zu einer Konsolidierung von Steuergeräten. Gleichzeitig erfordert der Einsatz im Automobil hohe funktionale Sicherheit (ASIL-Level), was unter anderem robuste Echtzeiteigenschaften der verwendeten Hard- und Software voraussetzt. Als Folge dessen werden zur Trennung von harten und weichen Echtzeitsystemen auf derselben Hardware Hypervisoren eingesetzt. Dieses Paper beleuchtet die Latenzauswirkungen diverser Softwarekonfigurationen auf Hardware der nächsten Generation mithilfe eines vorgestellten Testsetups und dessen Ergebnissen.
