it is too late for IBM to do an ARM now. Too much of a head start, may work if bare isa is licensed free. Besides new Isa's like UCB's riscv are a better and cleaner option, besides being free. In fact for our open source processor, we did a ppc implementation but later switched over to riscv. Patents are not an issue in India but if we wanted our processor to be adopted worldwide, they can be a problem. In fact a whole bunch of universities are collaborating to get these open source processors out. That could potentially eclipse ARM. The adjunct story to that is the Chisel hardware development language from UCB. It is based on Scala and is again completely free. Use off scala opens up the programmer base to a wider audience compared to say System Verilog. In fact the US govt is also keen to see this language succeed. So now all you need is a PC and a bent for processor design and you can churn out your own custom cpu. A basic fpga board will do for a sub 500 MHz processor. Our lab results show 200 MHz is trivially achievable. The point is that commercial grade cpu code will now be open source, so most folks just need to tweak it, not write a CPU from scratch. We also plan to open source IP like PCIe,DDR3/4, RapidIO, 10ge. Hopefully someone will do a gpu. See riscv.org . UCB plans to finalise the ISA in Sept.

@GMSD: Interesting. I saw a Berkeley poster on Chisel and RISC-V at Hot Chips. They plan a September bot camp. But what's thre route to making this commercially viable?

As folks said at the event, we are at a stage where no one has motivation to drive a new ISA.
 BTW, Nividia announced earlier this year it will license its Kepler GPU IP.

@SSLIVA: Funny I forgot the Goog/Mot connection. The PowerPC partners are back!

Perhaps IBM pulls through at least in part because it has the pockets -- and the foresight -- to think ahead -- way ahead. As the NYTimes recently noted, "I.B.M. was granted more patents in 2012 than any other company, **the 20th consecutive year in the top spot**". Personally, I have the pleasure of writing about IBM on a regular basis -- at least the folks I'm in contact with -- those working on their chips and basic science stuff -- are insanely smart and innovative. And as a company, they always seem to have an ace in the hole. They understand Big Data as few do. Last stand? To borrow from Mr. Twain, I think that falls into the domain of great exaggeration.... IBM is, was and always will be an amazing company.

That is completly and utterly sad, it sounds like Dilbert was written by an IBM insider :-(
