RISC-V benefits is mostly an open source license that is free of patents. I think the biggest reason for it is academic... there needs to be an open platform for academic research. I'm sure it is next to impossible for an average university to do that on ARM or x86 architecture.

RISC-V is just ISA. I don't think ISA's can be patented. Just some specific instructions.

Yes, they did the research for prior art to make sure that is the case for their instruction set.

I haven't been following the RISC-V story too closely, possibly because I didn't want to get my hopes up only to be dashed. From the article, it sounds like these cores will be developed solely for use in data storage. Can someone with more knowledge tell whether this will help provide the kind of production volume needed to make consumer products (like laptops and desktops) more likely to be viable? Are general purp…

Probably we won't be seeing RISC-V application processors for quite a while. There's a lot of stuff that can just be recompiled but there's also a lot of hand-tuned assembly that goes into making a JIT or media codec fast. That's why we're seeing initial adoption in the embedded space, where either there's just a small amount of code to recompile or you were going to rewrite the assembly anyways for the next product.

In the long run using RISC-V in a laptop is a possibility. And there might be some limited production $2000 500MHz FOSS laptop soonish. But in 15 years, say, I could see RISC-V being where ARM is now.

>> Why do people downvote? Because they can't handle the fact that you're right. RISC-V is coming for all of them. I like your phrasing too, it's accurate but I guess people think it's more pretentious. Only time will tell for sure.

There's a lot of wishful thinking involved in this. It's like Linux on the desktop: doable but very much a fringe thing.

>> There's a lot of wishful thinking involved in this.

Yeah I agree, but the list of giant companies involved in the wishing is what makes it seem like more than a pipe dream. Just think how much revenue ARM will lose when WD, nVidia, Samsung and others all switch to RISC-V in their embedded devices.

Were there any academic obstructions to OpenRISC or OpenSPARC?

From the headline, I would guess WD is putting a user accessible CPU in each of their disk drives, idea being that if you have a CPU living close to the drive, then e.g. map+reduce workloads can be more efficiently executed. Instead of going with ARM or Intel, I guess the CPU's are using some less famous architecture called RISC-V. Then I read the article, and the article is so full of buzzwords and genericisms that…

In order to move the reader head inside your drive and to communicate with the host CPU you need microprocessors in your hard driver, really tiny ones. Now, instead of paying ARM for licences to use them WD is using open source processors that don't come with fees besides what it takes to manufacture them.

I think the level of industry enthusiasm for RISC-V is so palpable, in part, because the messaging from day one has been unequivocally: RISC-V will be the standard ISA for every form factor, in every market. Can't wait to put a RISC-V SBC in my ThinkPad X220 chassis. :- )

I'm so excited that we're feasibly within a year or two of being able to develop embedded devices in Rust[0] on RISC-V microcontrollers [1] running on open source RTOSes also written in Rust[2]. It's currently already possible but still requires quite a bit of hacking. Plus the RF stacks (Bluetooth in particular) aren't there yet. What a time to be a developer. PS RISC-V on my X220 wouldn't hurt either.

This was what I exactly predicted one year ago. Risk-V ISA is coming for all of them{x86,arm,mips}. And this is very smart move by WD to jump into Risk-V wagon. Update: Why do people downvote? I honestly don’t understand.

Even though I see no reason to vote you down, there are a lot of reasons not to vote you up.

The message from WD is very good news for RISC-V. But to make the claim that it overthrows all other architectures from the throne is not only a bit daring. With this logic, ARM should have crashed Intel a long time ago. There will always be a market for different architectures.

You have also misspelled RISC-V, indicating that you are not really aware of the market and architecture.

So WD is switching their hardware to in-house designed processors after purchasing a RISC-V developer, do I understand this press release correctly?

WD had already been a RISC-V foundation member before their involvement with Esperanto Technologies (who has also been a member for a while). I suspect they saw Esperanto's portfolio and team after meeting at one of the workshops, and bought into it because of preexisting interest in RISC-V.

Just to be clear, I think they bought into Esperanto, but I don't think they acquired it. Much public communication implies that Esperanto Technologies is still generally autonomous[0][1].

I haven't dug through all the marketing speak yet but this seems like it's tangentially related to WD's He8 converged servers they've been sampling, which were ARM-based and ran Debian Jessie. [0] Although when I saw them spoke about in Redhat Summit of course they were mooted to be running RHEL. It would be interesting to see if WD Labs is now sampling RISC-V-based boards running Redhat and Ceph OSD software which like the He8.

I found the whole concept of on-board PCB with dual gig ethernet ports fascinating and I believe there's a second generation with faster network speeds. Unfortunately WD never seem to have gone mainstream with it.
