Sun Niagara 2 CPU Now Open Source
downix writes "Late last night Sun Microsystems announced the immediate availability of the UltraSPARC T2, also known as the Niagara 2 CPU. While we all might not have a silicon fab in the basement, the access to this source code reaffirms Sun's commitment to open source, and in addition gives us FPGA-lovers something new to play with. The source code can be downloaded (with registration) from OpenSPARC.net. Already the previously open sourced T1 has spawned spin-off projects, such as the Simple RISC S1."
A billion is low-end fabs. High end cutting edge or even near-cutting edge technology costs much more. Maybe a billion for "old-school" tech like 130nm.
No, your best bet is to just pay the few million to have someone fab it for you - there are very few companies that have their own fabs and can do it inhouse (e.g., Intel, IBM, AMD, Freescale (Motorola), Samsung, Toshiba), at least, cutting edge fabs. Low end fabs can be had for cheap (1um and larger), which is great if you don't particularly care about density (e.g., Gemplus - those smartcards have HUGE silicon for 32k memory and not much more).
Most companies are fabless. They contract out the fab work to places like TSMC (amongst others - they're all well known). These include even heavyweight giants like nVidia, Altera, Xilinx and such. The only real downside is that delays can happen if machinery breaks down, or everyone submits a fab order simultaneously that causes backups at the fab and thus delays shipments. The turnaround time (from tapeout to getting chips back) can be 3 months or more. Luckily, most people test their designs out on FPGAs first to work out their bugs before committing them to silicon. Even places like Intel use computer simulation, discrete circuits, FPGAs, and such before they fab it out to their own fabs just because of the turnaround time.
Of course, what I want to know is what's the smallest FPGA one can put this on and still have something workable. (Where things like bus timings and memory clocks still in the realm of "practical" and "in spec").
Actually, the cost for one-offs is significantly lower than your estimate.
By using a Shuttle run, where the fab batches together a bunch of designs and runs them through using a single mask set, you can get 20 or so instances of a 130 nm design for roughly $100K. Of course, this assumes that you've already done the layout and verification steps yourself...
And the worms ate into his brain.
How big an FPGA would be required to run this? Can you really download the configs and run it on an FPGA at a reasonable speed? Which Xilinx model?
How about running Linux on that simulated Niagara2, like you can uCLinux on a Microblaze? The exciting part would be replacing parts of the OS, like the TCP/IP stack, with "HW" configs for really high performance, customized per app. None of your processes use some dozen instructions? Drop their microcode in favor of a faster multiplier...

Hardware. I transitioned all of my company's servers to Sun (when they started selling x86 servers) over the last few years, and I couldn't be happier. The equipment is more expensive, but it is also of a superior quality and features real enterprise management features. Opening up Solaris had a lot to do with my initial decision, and I wouldn't be surprised if we don't transition to the T2 in the future. Since all of our servers are virtualized anyway, it isn't really a bad idea to move lots of small servers to a few big servers, and this open architecture will undoubtedly give some experts the opportunity to publish very in depth analysis of the chips.

Niagara 1, had one FPU per chip. Niagara 2, has more than one.
The way you pose it -- doesn't perform unless you can find the parallelism -- is not the right way. Some clever person found a market where there was parallelism, and that turns the problem around. "Given that I have all this work to do, what's the throughput per watt?" Niagara wins there. And it happened that those people, or a lot of them, didn't have a burning need for floating point.
Or to use a lame car analogy, a schoolbus is no good unless you can find 32 kids to haul, whereas a minicooper is cool and zippy with only two. But if you regularly have 32 kids to haul, and some people do, you want a schoolbus, and a minicooper is not very efficient.
I've had this position for about 2 years now.
IMO, Sun is one of the only companies left innovating.
-Google is just rehashing old ideas.(Gmail? come on....I had webmail 10 years ago.)
-Oracle(eh... RDBMS v45.2 anyone?)
-IBM(If I see one more pointless black-and-white commercial about "ideas" I'm going to scream. IBM should listen to their marketing department and instead of telling us to "Stop thinking, start doing" they should create something that isn't AIX)
And, I will be the lone voice and dare to say that Microsoft, yes them, has a few teams that are starting to 'get it'. Apple is doing a great job with human-computer interaction.
Show me new, for I am tired of your old.
