Floris Itsme! meldt dat AMD vandaag de x86-64 specificaties gepubliceerd heeft. De aanpak die AMD heeft gekozen om 64-bit te kunnen gebruiken is een uitbreiding van de x86 instructieset zodat ook 32-bit programma's zonder problemen kunnen blijven werken. De voordelen van 64-bit zijn: meer adresseerbaar geheugen en de mogelijkheid om 64-bit getallen te verwerken. Daarnaast heeft AMD ook nog wat extra instructies toegevoegd om zo de FPU performance flink te verbeteren.

SUNNYVALE, CA--August 10, 2000--AMD today publicly released the x86-64™ Architecture Programmers Overview, the instruction manual the software community can use to begin incorporating x86-64 technology support in their operating systems, applications, drivers and development tools. AMD’s x86-64 technology will first be supported in the family of processors codenamed "Hammer," planned to be announced at the end of 2001.
"Sun Microsystems’ Solaris team is very excited about AMD’s x86-64 technology. We applaud AMD’s ISV compatibility and upgrade strategy as well as their open technology announcement today. We will be following their progress closely as this technology comes to market," said Anil Gadre, vice president and general manager for Solaris at Sun Microsystems.
[...] "Perhaps the most noteworthy feature of AMD's approach to 64-bit computing is that it is an extension to the 32-bit environment prevailing in the industry today rather than a radical departure," said Gordon Haff, a Research Director with the Aberdeen Group. "As the industry as a whole progresses to 64-bit platforms, we expect many system suppliers, software vendors, MIS managers and end users to be interested in architectural features that allow them to migrate at their own pace."
