Is this type of article interesting to you? I've been maintaining the simulator for this technology for the past year or two and my eyes glazed over when I went through the article.

To support port bifurcation efficiently, the bit lanes are swizzled to avoid excessive wire crossings which would require additional layers in motherboards.
Is that a technical term? Searching on reference.com shows lots of definitions for tall drinks, possibly with swizzle sticks, and even gulping them down... There's one reference to converting indexes to address pointers, but I'm not sure how that applies to physical routing...

If that is a legit technical term, I'm gonna have to find some way to use it in my next interview :P Or maybe, I'll go find some snizzle to swizzle

Sure, I use it technically.

If you have bits:

15 16 17 18 19 20

and you change them to

18 19 20 15 16 17

or some other simple transformation, I'd call that swizzling. Shuffle is also appropriate, but I tend to think of shuffle in terms of bytes and swizzle in terms of bits.
