Arithmetik in Rechenanlagen
Dieses Buch entstand aus einer Reihe von Vorlesungen und Seminaren an der Universitat Saarbrlicken. Es enthalt eine vergleichende Be- schreibung von schnellen und kostenglinstigen Algorithmen zur Reali- sierung arithmetischer Operationen in Digitalrechnern. Obwohl fast aIle Informatiker und nicht wenige Wissenschaftler an- derer Fachrichtungen mit diesen Problemen mehr oder weniger inten- siv konfrontiert werden, behandeln deutschsprachige Fachblicher mit allgemeinerer Zielsetzung diese Fragen nur am Rande oder in ver- gleichsweise kurzen Kapiteln; dies flihrt zwangslaufig zu einer Be- schrankung auf die Beschreibung der bekanntesten und einfachsten Verfahren. In der englischsprachigen Literatur gibt es zwar mehre- re ausgezeichnete Standardwerke (zu erwahnen ist hier in erster Li- nie Flores "The Logic of computer Arithmetic"), doch sind diese oft nur schwer zuganglich und meist alteren Datums; viele wichtige Re- sultate wird man dort also vergeblich suchen. Der Mangel an neueren Blichern liber Rechnerarithmetik kann nicht dar auf zurlickgeflihrt werden, daB aIle interessierenden Probleme be- reits in Standardwerken abgehandelt sind: die Anzahl und die Rele- vanz der in jlingster Zeit veroffentlichten Arbeiten beweist das Ge- genteil. Die Hauptursache daflir liegt nach meiner Ansicht vielmehr in der oft uneinheitlichen Darstellung und der zu starken Beschran- kung vieler Arbeiten auf ein bestimmtes Maschinenkonzept oder auf eine zur Zeit verfligbare bzw. in Entwicklung befindliche Baustein- serie, wodurch eine zusammenfassende Ubersicht sehr erschwert wird.
