Harte Echtzeit für Anwendungsprozesse in Standard-Betriebssystemen auf Mehrkernprozessoren

  • Conference paper
  • First Online:
Herausforderungen durch Echtzeitbetrieb

Part of the book series: Informatik aktuell ((INFORMAT))

Zusammenfassung

Wir stellen einen neuen Ansatz vor, um harte Echtzeit-Tasks auf einem gewöhnlichen, unveränderten Betriebssystem auszuführen. Dieses Vorhaben kann durch Isolation eines einzelnen Prozesses auf einer CPU realisiert werden, indem alle Interrupts blockiert werden. Da Systemaufrufe ein unberechenbares zeitliches Verhalten verursachen, nutzen wir Kommunikation über gemeinsamen Speicher. Dadurch können Entwickler von Echtzeitsystemen von aktuellen Mehrkern- Prozessoren und Betriebssystemen profitieren, um Anwendungen mit Echtzeit-Tasks und hoher Rechenleistung auf marktgängiger Hardware zu realisieren.
