Bloomberg is reporting that this isn’t going ahead.

https://www.bloomberg.com/news/articles/2021-10-21/intel-s-talks-for-chip-designer-sifive-said-to-end-without-deal

I think this is a good thing, actually:

  • Intel really ought to have the skills necessary to design a RISC-V chip. And
  • SiFive won’t be consumed and then neglected as often happens in these cases.

nooooooo

that sucks.

But why should this be bad? As the comments point out, RISC-V will still be a libre ISA, SiFive did not make libre hardware and there might be a good outcome to this. SiFive has not proven to be of special worth.

Interesting, thanks for your answer. What did you mean with “(risc-v BTW is not a libre ISA, it’s an open ISA)”?

RISC-V is an Open Source ISA, but companies are at liberty to use it proprietorially…

In fact, they can use it, and not disclose that they are doing so (so long as they don’t use the RISC-V label, it doesn’t need to be verified).

I think that a lot of SiFive’s chips are actually closed-source… so in that sense, no different to Intel’s work. :(

I honestly don’t understand what’s going on here…

When Intel lured Sunil Shenoy back from SiFive, I thought it indicated that they were interested in RISC-V as an alternative to their faltering X86 architecture.

Since Micro Magic’s demonstration of RISC-V’s capabilities at the end of last year, I’ve been waiting for Intel to announce that they’ve developed a RISC-V chip that can blow Apple’s M1 out of the water… I thought that they might try to use Micro Magic’s know-how - not SiFive’s!

Since RISC-V is an Open Source ISA, I assume they’ve realised that this isn’t analogous to Nvidia’s attempted acquisition of Arm… They won’t get control of the ISA - US$2.1B only buys SiFive’s brains and their (software) IP. (And the brains might not stick around for very long after the acqui-hire.) There is no consolidation of tech in this purchase.

Does Intel really need SiFive to develop a RISC-V chip? I don’t believe they do.

So what’s going on?

So I guess the question to ask is:

What Intellectual Property do SiFive have - that Sunil Shenoy would know about - that would be worth >US$2Billion to Intel?*

And two possible answers occur to me -

Either - They’ve got the next generation of DataCentre chip

Or - They’ve got an Apple M1 beater SoC that hasn’t been released yet, because the software is still inchoate.

*Other than the significant intellectual brainpower of their engineers.

RISC-V (pronounced “risk-five”) is a license-free, modular, extensible instruction set architecture (ISA).
