Hi; How does the cpu search and find stuff? I am asking at the lowest abstraction level and hardware level. I have read several operating system texts and have an overview understanding of 'C'. There is a huge amount of searching and finding of text in memory, conditional statements requiring comparisons, and the use of entry points but not exact addresses from within both kernel space and user space. It has occurred to me that a there is necessarily a lot of physical or bit comparing going on. Too much, I would think, to keep dumping a search criteria into a cpu register and then replacing the contents of a second register from a block of memory until one matches. I understand the use of hash tables. I am asking at a level lower than that. Is there a special unit within the cpu or memory were rapid comparison, or partial comparisons are made during a search, before a criteria is noted as found and moved into the cpu registers? In a generalized way, at the hardware level, how are searched for criteria found? I have googled for an answer and found nothing helpful. That usually means I have somehow mis-posed the question, am working from wrong assumptions or lack the correct terminology. Help chasing the 'searching' mechanism would be appreciated. -- Regards Bill Fedora 13, Gnome 2.30.2 Evo.2.20.2, Emacs 23.2.1 -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
