Understanding 64-bit PowerPC architecture
An anonymous reader writes "Each of the leading microprocessor manufacturers has announced the availability of one or more 64-bit desktop processors, but differences exist in architectural design, fabrication, support, and intended use of each processor. This article looks at the critical issues in a few of IBM's 64-bit POWER designs, covering 32-bit compatibility, power management, processor bus design, and the manufacturing process."
It's a dupe.
Power != PowerPC That is all.
Isn't this the same story as five stories ago? Am I missing something?
``64 bit PowerPC architecture...desktop...POWER''
but wait...I thought PowerPC and POWER are similar, but not identical, and that PowerPC was aimed at the desktop, whereas POWER is more for servers. Do I have it wrong?
Please correct me if I got my facts wrong.
That is the first time I've seen a dupe at the same time as the original is on the front page. Wow again.
-._''_.-
The fastest dupe I've ever seen.
a dupe posted by CmdrTaco to a story posted by Hemos.. It feels like 1998 again :-)
i think they did that because the other link is still loadable
unlike the watercooling article
Admit it! Some of you send in stories that are on the front page just to see if they get duped, right?
I'm on to you!

Yeah but that was on april fools' day and doesn't count. They were doing that on purpose.

they're means "they are"
there means not here.
First, I'm talking a risc/cisc architecture like the x86.
:P.
When you're talking about 64 addressing lines, your talking about addressing a fscksum of memory and devices. But, in addition, those lines allow for other possibilities: for example, sending 2 or 3 write commands with attached data and 2 32 bit addresses on the 64 bit bus simultaniously with an extra address decoder either on the chip or on the memory controller, or to some other device. Although, I don't know weither or not they've thrown that in as of yet. 64 bit numbers don't occur that often, afaik, but I'm not a coder so
The data bus advantage, however, is bigger. The x86 architecture has a command decoder, whereas you can send several commands in a single clock. With 32 more bytes, you get twice as many commands in a clock. Additionally, you can address more commands (but seriously, the first x86 had 38 commands, and that has increased by 10x in the past few years).
Aside from that, you're throwing on more features into the processor. But, that's been here in the past 20 years of processor developement anyway. The article tends to be unclear on this. You're essentially expanding the bus to feed more buffers/pipelines.

no. It's not a dupe, it's the 64 bit bus sending the same 32 bit information, doubled up along the bus. It's just looks like it's posted twice. It's much more efficient this way. Trust us!

In the abscence of institutional memory or /. editors sitting in the same room :-) , could Slashcode be tweaked to scan for URLs that are identical in stories and flag them somehow?
Some Perl script or such that looks at the post about to hit the front page, then looks at a say the last three or four posts that were on the front page. If it finds an identical or closely identical link, it then sends an email of the body of the two posts to the editor.
I don't think it would get the server's load up too much.
