Als Beispiel f\u00fcr die Verwendung von ACRN werden elektronische Steuerger\u00e4te, Armaturenbretter und Informationssysteme f\u00fcr Fahrzeuge genannt, aber der Hypervisor eignet sich auch gut f\u00fcr Verbrauchs-IoT-Ger\u00e4te und andere Embedded-Anwendungen. <\/p>\n<p>ACRN bietet minimale Overheads und besteht aus nur 25.000 Zeilen Code (zum Vergleich haben in Cloud-Systemen eingesetzte Hypervisoren etwa 150.000 Zeilen Code). ACRN gew\u00e4hrleistet dabei niedrige Latenzzeiten und angemessene Reaktionsf\u00e4higkeit bei der Interaktion mit der Hardware. Es wird die Virtualisierung von CPU-, Ein-\/Ausgabe-, Netzwerksubsystem-, Grafik- und Audiooperationen unterst\u00fctzt.
