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."

Ehh?

``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?

Re:Power != PowerPC

[m0rph3us0]

The Power processors implement the PowerPC instruction set.

What you are saying is like saying Pentium 4 != x86

You can run OS X on POWER processors through Mac on Linux. And the PPC 970FX is a derivative of the POWER4 processor.

Basically, the PPC 970 is a POWER 4 with a better SIMD unit.

dupe detector?

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.
