Re: Who said Itanium had or is going to have SMT?

Would it be reasonable to suggest that Itanium does SMT in software regardless of whether or not it also does it in hardware?

Tenchusatsu, Re: "Who said Itanium had or is going to have SMT?"

Paul Otellini did. At IDF. You can check his keynotes on the web. They were very interesting.

Dumbmoney, <Did the Unobtanium FP registers shrink while I wasn't watching?>

No. How many FP registers did you think Itanium had?


The question was not how many, but how big. You said 64 bits. I thought they were 82 bits or so, but it's been 4 years since I read the spec.

<I wonder if SMT will be hard(er) to implement because of the large number of architectural registers.>

Who said Itanium had or is going to have SMT?


Well, certainly CPUs in general are going in the SMT direction. Maybe IA64 will die out before it matters.
