SIMD predates both Alpha and x86. E.g. the VAX 6000 vector processor
did SIMD, as doubtless did others less familiar round here.

That said, there have been a number of patent disputes between DEC and
Intel. I don't remember SIMD being mentioned in any of them, but that
may be my memory at fault.

Also due to unreliable memory, I cannot remember the Intel executive's
name or exact words but I do remember one of them once said something
functionally equivalent to "our chips are so advanced now that we've
run out of ideas to copy". Suggestions welcome - it was reported in a
few journals and probably referenced in this ng but I can't easily
find it just now.

Yes there are SIMD instructions in Itanium; the published
documentation has details (and doubtless other sources too).
