Sun Microsystems plans to release on Tuesday the underlying design of its UltraSparc T1 "Niagara" processor under the terms of the General Public License.
The move fulfills a commitment to employ the widely used open-source license that Sun President Jonathan Schwartz made at the Open Source Business Conference in January. David Yen, executive vice president of Sun's Sparc server group, is expected to discuss the move at the MultiCore Expo, which runs Tuesday through Thursday in Santa Clara, Calif., where Sun also has its headquarters.
Sun's UltraSparc T1 has eight processing engines, called cores, each able to run four simultaneous instruction sequences, called threads. When one thread stalls because it has to retrieve data from comparatively slow memory, a core switches to another thread. This approach is designed to let T2000 and forthcoming T1000 servers run many jobs in parallel with good performance, even though an individual job may not get done as fast as on a more single-minded chip.
The OpenSparc project is designed to increase the relevance of Sun's Sparc family, which has lost market share in recent years to Power chips from IBM and to x86 chips from Intel and Advanced Micro Devices. Sun hopes that making the designs available in the Verilog format will trigger research projects and commercial development.
The General Public License (GPL) was developed by Richard Stallman and is a cornerstone of his free-software movement and the closely related open-source software concept. It lets a program's underlying source code be seen, modified and distributed by anyone, so long as anyone who distributes a changed version publishes those changes under the same license.
One company, SimplyRISC, plans to make a single-core version of Niagara for embedded computing devices, which often require low power consumption. And a chip design company called Aldec plans to make its Riviera software available for 90-day free trials so people can simulate Verilog designs.
In conjunction with the chip designs, Sun also has published at its OpenSparc.net site the UltraSparc Architecture 2005, which defines the set of instructions the chips can execute. In addition, the company has published verification software and simulation models to test software on chip designs, as well as a version of its Solaris 10 operating system that can be used in such simulations.
fyi
Anyone know what that means?

From Verilog.com:
What is Verilog? (Ref. The Verilog FAQ, Author's experience)
Verilog HDL is a hardware description language used to design and document electronic systems. Verilog HDL allows designers to design at various levels of abstraction. It is the most widely used HDL with a user community of more than 50,000 active designers.
I'm not sure what platforms run software to read it.
I just looked at the installation instructions on the above site, and it appears to be an Emacs plugin of some kind. I've never done much in Emacs (I'm a 'vi' kind of guy), but I wouldn't be suprised if it was pretty powerful, given what I've seen people do in Emacs.
OK, thanks.
Sun has done some of the dumbest things lately, and if this allows foreign governments to build their own CPU's without Sun's consent, it might be their dumbest move yet.
Do a google search on Verilog Format.
SOCcentral brings you the latest news about SOC/ASIC/FPGA design, EDA tools and design methodologies
That's enough.....
^^^^^^^^^^^Sun has done some of the dumbest things lately^^^^^^^^^^^^
Still the armchair CEO eh GE?
I'm obviously a lot closer to CEO than any of you software beggars will probably ever be.
Delusions of grandeur.
You'd make a nice CEO of Enron, though.
Well flamer if you were making well over 6 figures like myself you probably wouldn't have to beg on the corner for free software. Nah, we know your kind, you're more likely to give all your work away to "the community", like that whacko Richard Stallman asks you to do.
"if you were making well over 6 figures like myself..."
Awww, listen at ya now. Grow up.
Obviously I am the grownup. Or at least the one that understands reality, and isn't a chump for whacko leftists like you.
Gimme a break. When you start throwing around statements like "I make six figures", you might as well be yelling, "My dad can beat up your dad".
Moron.
I knew a socialist wouldn't be impressed, unless you got excited about how much you could charge me for Stallmana's software tax.
Ha! I didn't get excited because you've proven that you'll lie about anything right to my face! I hardly trust you on any issue about which I have to take you at your word! Sorry you didn't get the attention you so desperately wanted on that one, but if you're really broken up about it, I can fake it...
Hilarious. This post made my day.
You don't have to trust me, go to communism.org or wikipedia.org, both of which admit open source like Linux is an example of communist principles.
