Abstract

Unconventional Computing (UC) denotes new and alternative methods and technologies for computer technologies, e. g., nanocomputing or DNA computing. This paper investigates the importance of UC for the Grand Challenges of Computer Engineering. At the moment nanocomputing appears to be the most promising UC discipline. As example for an UC method the use of redundant arithmetic and reversible logic for nanocomputing is presented.

Zusammenfassung

Unkonventionelles Rechnen bezeichnet neue und alternative Methoden und Technologien für die Rechentechnik, z. B. Nanocomputing oder DNA Computing. Dieser Artikel behandelt die Auswirkungen auf die Grand Challenges der Technischen Informatik. Es wird aufgezeigt, dass das Nanocomputing die derzeit aussichtsreichste Variante darstellt. Als Beispiel für eine unkonventionelle Rechen-Methodik werden redundante Arithmetiken und reversible Logik vorgestellt.

Keywords: unconventional Computing; nanocomputing; reversible logic; signed-digit arithmetics
