Intel hyperthreading traced to DEC tech

Nonetheless, technologies with Digital genes march on, including HyperTransport, a high-speed method of chip interconnection championed by AMD; a future version of Intel's Itanium family of processors; and low-power chips for cell phones and handhelds from both those companies.

Intel's hyperthreading, which involves breaking up an application for easier digestion by a computer's processors, derives in part from work on simultaneous multithreading performed by a team of researchers at the University of Washington and Digital, an Intel representative confirmed. In 1997, Intel licensed the patents and hired many of the employees who worked on the project as part of a massive legal settlement between the companies.

Full story.

What else has been borrowed, re-invented and / or bought? 🙂
 
you mean Aliens, right? 3D Tri-Gate Transistors? think about it...

Einstein also got relativity from aliens.

they actually built a time machine and went into the future and stole AMD technology and came back and made sandy bridge 50 years before AMD made it.

Too bad AMD dosnt know they are competing with there own technology

just like how some dudes from 1997 have anything to do with how advanced intels hyperthreading is today

They had a time machine and they did not foresee and prevented the Cougar Point massacre? :hmm:

yeah if AMD is capable of making Sandy Bridge in 50years, I'd be pretty happy for them already. Sadly, at this pace, they'll be lucky if they don't regress to stone age soon.

the core architecture came as a result of some new startup team in Israel or something. They bought them and their IP out.

Um, no. Intel Haifa has been part of Intel since 1974. The team had just come off of the cancelled Timna project (which, by the way, had an integrated memory controller) when they were assigned to create a backup mobile processor Banias to the Pentium 4. They based Banias on the P6 (Pentium Pro, Pentium II) architecture. That project was released as the Pentium M and later evolved into the Core 2.

Well, you know, there was a lot of forum speculation that Intel had to have known about the issue ahead of time to have announced and shipped a Cougar Point fix within a month of announcing the recall. So there you go, that conspiracy theory has more legs!
 
It seems like you're insinuating that this is wrong some how? Any tech that needed licensed was licensed. What's the issue?

I think SMT must started from some university project, not from some company's idea.

Wiki says IBM in 1968.

While multithreading CPUs have been around since the 1950s, simultaneous multithreading was first researched by IBM in 1968. The first major commercial microprocessor developed with SMT was the Alpha 21464 (EV8). This microprocessor was developed by DEC in coordination with Dean Tullsen of the University of California, San Diego, and Susan Eggers and Hank Levy of the University of Washington. The microprocessor was never released, since the Alpha line of microprocessors was discontinued shortly before HP acquired Compaq which had in turn acquired DEC. Dean Tullsen's work was also used to develop the "Hyper-threading" (or "HTT") versions of the Intel Pentium 4 microprocessors, such as the "Northwood" and "Prescott".

And how exactly is this news?

Edit: lol, apparently the article is from October 2002 and this fact had already been raised. What a worthless thread.

HT still doesnt worth the extra $$ compared to full cores. Cores > HT, nough said.

Yes, two real cores beat one with hyperthreading- but also use far more transistors and take up more die space. For the increase in transistor count, hyperthreading is a worthwhile improvement.

Exactly. For many mainstream PCs, 2C + HT is the 'sweet spot' for most users. This equates to 3-4 similar speed cores from AMD (Ph II X3 or X4) and what many users would recommend to their friends who do standard tasks and may want to do some gaming as well.
