AMD 64BIT CPU....DUAL 32BIT PIPELINE.
Hello all,
Im a part time computer technician and have a couple of problems/questions
I understand basicly how the 64bit CPU's work compared to a 32bit CPU. But seen as the general user/gamer does not require such wide pipelines is it possible to run a linux or similar core and then run 2x seperate Windows XP 32bit version O/S's. So i could in other words ALT-TAB between two seperate 32bit O/S's. therefore sorta doubling the amount of 32bit data processing that can be done at once.
For a better example of what im getting at...
I want to process a home video stream (xvid to mpg conversion) in one 32bit O/S (as the software will only run on 32bit cpu (i know 64bit are backwards compat)) at the full CPU speed. say (AMD XP) 3200mhz and in the other O/S (shell) play games without jerky movements. It is possible to do that to the 64bit CPU's and not have data sync probs or processing errors?

Thanks very much
Brad

You might be interesting in looking into the "Pear" systems (i.e., crossbred PC/Mac running live) .. short of that, unless you feel like writing your own "master" OS ... no.

As for the "64bit" being two "32bit pipes", that's not the case. A quick example can illustrate:
[0] A 64bit CPU offers 64bits ... namely 0 to 63
[1] Suppose we have a 32bit OS. It can handle bits 0 to 31.
[2] Suppose we have another 32bit OS. It can handle bits 0 to 31. However since those bits are "taken", this OS is shitcanned. :P
[3] You cannot "shift" bits around :)


it could be but i cant really see the point of it

How might you consider doing this?
