    This seems to be run by a random dude looking for funding:

    About ERICI

    ERICI is a non-commercial initiative in its founding phase. It is not yet a legal entity, sells nothing and charges no fees.

    (https://erici.eu/impressum.html)

    • ymz515 hours ago
      Have you noticed the words "non-commercial" at the bottom of the page?

      The random dude is not looking for funding.

      • dathinab15 hours ago
        non-commercial doesn't mean not looking for funding (neither does it mean looking for funding)

        it means not intended with the purpose to make money from it

        founding doesn't always imply. a startup-like process of selling stock (or similar) to investors which in turn want some profit from it long term

        it can also mean looking for donations to found a project, i.e. cover it's costs

    Author here. Happy to answer technical questions: about HFI BIOS, partitioning hypervisor (gRouvr), QSOE RTOS.

    I hope that leading European industrial computer manufacturers notice the initiative and join -- or at least start evaluating the possibility to use RVA23 SoCs in their devices. Yes, currently only Chinese vendors can provide such chips, but the world is changing fast.

    • RetroTechie11 hours ago
      Why the emphasis on RVA23? Since when are vector instructions a minimal necessity? Plain RV64GC is mooore than powerful enough for industrial/machine controllers & the like - assuming a standard sw/hw platform.

      What's missing here is the "made in Europe" bit. Currently (very few exceptions), RISC-V SoCs are designed by Chinese companies, maybe fabricated in Taiwan, and boards they go on manufactured in China.

      Imho that is what Europe needs to address. With EU-made boards available, the software side is the easy part.

      There is some European CPU initiative. Sounds great but where are the boards?

      • ymz511 hours ago
        > Why the emphasis on RVA23?

        Easy. In fact, the emphasis will be on RVA23 _and_ on working IOMMU hardware. This is needed for hardware resource isolation between operating systems running on the hypervisor.

        RVA23 is mandatory for Ubuntu, for example. So the requirement is not new at all.

      • petra11 hours ago
        My guess: The goal is EU industrial infrastructure . In that context, a somewhat more expensive cpu doesn't matter much, but if the same chip can cover more use cases, it ensures more volume and better protection against obsolescence.

    • sigmoid1017 hours ago
      Compared to x86, which is wholly owned by an American duopoly and needs licensing to produce legally, boosting RISC-V is a major step towards chip independence for Europe. With the current state of the US it almost seems a necessity. The only downside here is that it didn't happen sooner.

        What about ARM? Isn't it also European?
        • lioeters17 hours ago
          While ARM Holdings is based in Cambridge, England, it is majority owned by SoftBank Group which is a Japanese investment conglomerate.

          What's important in the context of a European "sovereign computing" initiative is the licensing of the instruction set architecture. Like x86, ARM is still proprietary, while RISC-V is a free and open standard.

          • pepperoni_pizza17 hours ago
            SoftBank is technically hedquartered in Japan but it is mostly owned by Saudis.
            • Imustaskforhelp16 hours ago
              This statement seems to be factually untrue. Mashayoshi Son owns 32-33% of Softbank and then the investors are like the Japanese Master Trust bank etc. Saudi Arabia is not even in top 10 of the investors list.

              Saudi Arabia did recently invest 45 billion dollars in the vision fund which is an investment fund managed by Softbank but they haven't really invested within Softbank itself so not it is not mostly owned by Saudis from what the data can tell.

        • LeFantome12 hours ago
          Others have already talked about the Japanese and Suadis.

          My point would be that it has already been demonstrated that you can lose access to ARM technology as a consequence of US sanctions.

          ARM is not a sufficiently independent ISA to guarantee sovereignty.

          With RISC-V, you may lose access to a specific core, chip, or supply chain. But your ecosystem can pivot to an alternative. Long-term, you have the option of complete in-sourcing.

          So, even working with Chinese chips and boards today can be progress, as long as more domestic RVA23 options can be expected to arrive later.

        • Danox7 hours ago
          It was British until a short-sighted company sold it to the Japanese, the EU at the time was also looking in the other direction too.
        • hn_submit17 hours ago
          It is if you define the UK being in Europe (the continent). It isn't part of the EU as of today, although there's a good chance it will be again in the future.

          Even though it's Japanese-owned most of their R&D still takes place in England.

          • ishouldnotbutk815 hours ago
            You don't need to define the UK being in Europe. UK is and forever will be in Europe, full stop.

            I know that sometimes "European" is used as a synonym for "in the EU", but most of the time this is sloppy. Nobody in Europe thinks UK is "not European".

          • sylware15 hours ago
            ARM is still IP locked like x86_64.

            RISC-V is IP UNlocked. I bought RISC-V mini-boards (so cheap) years ago because I was planning to build my keyboard... but I am still on other projects... and there are even better RISC-V miniboard nowdays (better USB, more GPIOs... for a full fledge BFO-9000 keyboard!).

            What I am waiting for are RISC-V high performance micro-architectures which will use the best silicon node (desktop, mobile, and for servers it seems there are a few attempts). One of the main issue seems... the compressed instructions which should be removed as it increases implementation complexity significantly in order to apply some of the known high-performance optimizations (it is not anectodale if ARM removed thumb machine instructions).

            I like the idea, I code as much as possible things in RISC-V assembly now, and re-use a ton of code paths (at the assembly level!). I have even written a small RISC-V interpreter for x86_64 for static exes.

      • hn_submit17 hours ago
        Even if Intel licensed x86 no one in Europe would want to make them. Unless they're guaranteed a monopoly there will be no takers. European companies and conglomerates are extremely lazy and risk averse.

        All they want is to suck on the government's tit.

        • Danox7 hours ago
          Arm would be a better choice the problem in Europe isn’t tech the problem is mainly a lack of will, I hope someone will pick up the gauntlet. And I don’t mean the free pizza and beer approach ie Linux.
          • bigyabai6 hours ago
            ARM is a markedly worse choice than RISC-V for Europe. It's expensive to license, relatively inflexible, and not majority-owned by European firms.

            There is no tangible advantage to Europe adopting the ARM ISA for domestic chips at any scale.

    • myrmidon16 hours ago
      Such development boards are a completeley different thing compared to RVA23-profile RISC-V CPUs.

      This is like comparing an 48MHz ARM-Cortex-M0 with the CPU in your Macbook. Yes both of them are ARM cores, but the small embedded processor has very little RAM/Flash/clockspeed, no memory management unit, no cache, no modern RAM interface.

      Not even the instruction set is really the same, because you (typically) won't even have floating point instructions/registers on the small MCUs, much less vector instructions.

      The Milk-V Jupiter 2 mentioned in the post is basically a full-fledged Desktop CPU and it's price is not gonna be anywhere close to $2 either...

      • kragen11 hours ago
        You aren't going to be running ERICI's Linux on a Cortex-M0-like RV32E, no, but I'd think that most industrial equipment has a lot more need for RV32E or similar than it does for Linux.
        • myrmidon10 hours ago
          You can certainly do a lot even with low end CPUs in automation (and they are certainly used a lot there).

          But there's a lot of basically-desktop CPUs in industrial automation too, because those are not that expensive and very useful for higher bandwidth interfaces (think ethernet based), cycle times in the microsecond range (higher CPU clock gives you a much more generous cycle budget) and just a generally easier time doing anything where a FPU and memory helps (motion planning, driving some UI on a touch panel, etc).

          See:

    • ErikCorry13 hours ago
      These implement 16-register cut down RISC-V RV32EC_Zmmul instruction set. It's an interesting choice. I wonder if they can run Coremark or Dhrystone so one can get an impression of their performance at 48MHz.

      8k RAM, 64k ROM, compressed RISC-V insn set.

      Edit: Apparently it's a QingKe RISC-V with about 130 Coremark.

      • kragen11 hours ago
        They shouldn't have any trouble running Dhrystone, either. RV32EC_Zmmul is closely comparable to the Thumb-1 ISA implemented by Cortex-M0, but I'd expect a little lower DMIPS/MHz than a Cortex-M0.
      • hn_submit13 hours ago
        These are more than sufficient for simple control applications. I'm just wondering if I can run a small GUI on it driving an OLED display. That's what I'm gonna find out.
        • kragen11 hours ago
          I'm confident you won't have any trouble at all doing that. 8KB RAM doesn't sound like much, but it's plenty fast enough to make up for it unless your OLED display is huge and your graphics are very complicated. It's roughly 50 times as fast as the original Macintosh, but with one sixteenth of the RAM, a combination that you may find favors IMGUI approaches. Popular OLED display controllers like the SSD1306BZ have their own framebuffers onboard, so you don't have to regenerate the pixels dozens of times a second to refresh the display the way you do for VGA or NTSC.

    I don't quite understand. Has this been a problem for industrial machines? Can't they already run for 30 years and more?

    What exactly is this initiative looking to fix and improve? Besides of the basic idea of FOSS being good, and whatever.

    • InvisibleUp18 hours ago
      They can run, but if one of the computer-related parts breaks down your only choice is scrounging eBay for replacement parts because (as an example) the software is proprietary and it runs on a weird MCA card with really precise timing and strong anti-piracy measures.
    • LeFantome9 hours ago
      You need to maintain both the software and hardware. It is not just that time an installation may last but the time the ecosystem stays viable.

      There are many CPU architectures, even some that became quite popular, that have gone extinct. Some lasted less than 30 years in total.

      x86 has lasted decades but, as it relies on only one to two companies, it is not guaranteed to do so.

      But the biggest risk going forward is geopolitical. You may completely lose access to a technology even if it continues to be available elsewhere. If you are in Europe, technology from the US in particular may be a concern. I think that is the main motivation for this project.

      In the 90s and early 2000s server uptime might be counted in multiple years and extremes in the decades

      The industry can barely keep an npm update from breaking the world now.. and that’s build tools and environments and so it’s independent of “we use stable languages”

      Now add the possibility of political sanctions on ISA licensing and you have -

      Hardware that’s fails quicker and may not be available to buy, software that barely builds months later, and a world where the US president can sanction entities at will if they don’t comply…

      Yeah, open source isn’t all that’s required

      • renszarv19 hours ago
        I do remember a Freebsd 2.2 server, that after it's setup in 98, reached 800 days of uptime without any kernel upgrade, but the main reason for that, we were too afraid to do an upgrade, let alone a reboot, because if the server hadn't started, getting to it physically with a new boot CD, would have been a big issue. And that was the single server that the company had at that time, for a long time :)

          I've been wondering the same since the scandal that hit the French literary world a couple of months ago [0]. Until a journalist (anonymously) accused the author of having written his novel with AI, literary critics and fellow writers were fawning all over the book, and the book was set to grab most of this year's literary prizes.

          Then people like you and me, who read AI prose all day long, went and read the book, and we all immediately knew the book was, at the very least, heavily AI-generated. For a few tragicomic months, people were in denial, going on TV to defend his book and defiantly proclaiming that "a machine could not have written this", only exposing their insulated ignorance.

          Hence the question: do we dislike this style because we read it all day long? Was it originally pleasing (it probably arose out of RLHF), but then used excessively? All while famous French writers and critics had nothing but the highest praise for the book...

          Note: after the author could not prove authorship, his editor officially declared that he had, indeed, used AI to write the book [0].

    So European, right?

    I'm immediately thinking: there's got to be some sort of sovereign aspect to the initiative ... right?

    I mean, if there's one place you want a silicon stack that wasn't manufactured in China, it's most definitely in the guts of your industrial infrastructure (assuming you still have one, yes, point taken).

          It used to be the case China competed mainly on price thanks to low labour costs. These days they still compete on price but because of supply chain integration.

          If like me you dabble in hobby grade electronics you know how parts and services availability looks like here in Europe. We have only one component distributor now that UK left the EU. And even them (Mouser) if you try to order any advanced components that run at high frequencies etc tend to ship stuff from US warehouses.

          Dont get me wrong. I'm still amazed they can get an order to me from US to Poland for $15 and 3-4 days time. But if I lived in China I could walk to one of bajillion physical suppliers and have every component made available same day. If I don't want to overspend on my prototype I could buy used parts without having to wait 3 weeks for delivery.

          Then we have PCB manufacturing and assembly. It makes zero financial sense to use these services domestically. I'd love to support local EU industry, but I'm not spending 10x the cost for the privilege.

      > build a computer from scratch

      What would it take to make this possible, if not completely then at least move in the right direction?

      Aside from re-thinking computer manufacturing from the ground up.. RISC-V, or something like it, seems like the right idea as part of the solution.

      A lot of ST made ARM chips should be more or less EU made, or at least Western made

      That may be a high bar. Would all countries in the world collaborating, except for China, Taiwan and South Korea, even be able to do this?

    Yet another "initiative". I remember the European Processor Initiative that went precisely nowhere.

      Not an expert, but reading the article you linked it seems it was quite stressful?

      > EPI demonstrated several results just after the Phase 2 end in 2026.[11] SiPearl demonstrated the Rhea1 chip running a complete HPC software stack. The system booted on a test board, with a standard Linux distribution running with high-speed HBM memories and their associated hardware performance monitoring counters. It successfully executed the HPL and STREAM benchmarks, demonstrating the readiness of the complete Rhea1 hardware and software ecosystem for HPC workloads to power Exascale systems. Rhea1 features 80 arm® Neoverse V1 cores, more than 61 billion transistors (7.8 billion equivalent gates), built-in High Bandwidth Memory, with 4 stacks of HBM, 4 DDR5 interfaces supporting 2 DIMMs Per Channel, and 104 lanes of PCIe Gen5 interface: up to 6 x 16 lanes + 2 x 4 lanes. Rhea1 was selected for implementation in Jupiter, Europe’s first exascale supercomputer. The next version, Rhea2, was selected for implementation in Alice Recoque, the second European exascale supercomputer.

      And then more paragraphs how work was taken forward..

    RISC-V is inevitable.
    • cbolton15 hours ago
      Not sure this quasi-religious framing does RISC-V any good.
    • ex_machina14 hours ago
      This cultish nonsense is one reason I've stopped taking RISC-V seriously for desktop/server usage. There are other reasons too:

      - RISC-V is "open", except in none of the ways that matter to me. What I want is a well-documented platform able to run fully open software. RISC-V does not inherently provide the former and the latter has nothing to do with ISA. If anything, manufacturers seem to take GPL-licensed software, modify it then _not_ publish the modified source code.

      - Lately I've started to care a lot more about minimal software stacks that are easier to prove to work as intended. Part of that includes generating raw machine code and I hate the terrible immediate encoding especially for C instructions. Compare with x86-64 where you can just write the constant straight to memory. x86-64 would actually be a nice ISA if it were not for prefixes + lack of explicit instruction length.

      - It seems there is an excessive focus on hardware "simplicity" (for very small cores) while neglecting simplicity on the software side. I would benefit greatly from automatic bounds checks, checked arithmetic... and many "safe" languages would too. This "simplicity" apparently is also why the immediate encoding is so ridiculous.

      Is it though? AI can rapidly push through an objectively better standard if a group becomes motivated to make one. There’s no need to marry ourselves permanently to a mediocre design like we did with C interop.
      • cbolton16 hours ago
        By some coincidence RISC-V became successful just before/while AI took off, and I'm glad it did. The design is pretty good for low end cores and probably good enough for high end cores, so there's a chance it will become one of the dominant ISAs in the mid-term.

        We're probably getting to a point where AIs will just generate optimized binaries directly, so I'd rather have them generate them in a machine language that is human friendly. RISC-V being designed by humans with a focus on simplicity is close to the best we could wish for.

  • mosura15 hours ago
    How long do we keep RISCV going without facing that it has failed? We were supposed to be surrounded by M1 level RVA23 devices by now.

    The telling thing is in benchmarks the Loongson outperforms them, by a lot.

    • cbolton15 hours ago
      So it's late to deliver hugely complex cores according to some optimistic timeline? That's a weird measure of success. The ISA is successful in the low end and is seeing huge investment on large cores, though most of the promising companies are now focusing on AI or getting bought by large players like Qualcomm. So yeah it might take a while still before we see competitive high end consumer cores. I would still put my money on RISC-V rather than Loongson for the long term but we'll see.
      • kjs312 hours ago
        That's a weird measure of success.

        It's a far better measure than "despite all the years of unfulfilled hype and promises we'll absolutely have a smorgasbord of performant RISC-V cores Real Soon Now". Single core performance down in the Intel Core range? Needs 96 cores to even be competitive on a handful of benchmarks that don't equal a modern users compute needs? The competition isn't sitting on their hands, and RISC-V hasn't delivered the performance it's fanbois have told us is 'inevitable'. Loongson has at least managed late-2010s levels of performance.

        Maybe RISC-V will completely take over the embedded market. That's not a bad gig. High volume, tho slim margins, lot's of niches for lots of innovation (want to continue to go crazy with ISA extension? Not a big deal in the embedded world). But they're still selling billions of 8051s, ARM is ubiquitous but even they didn't take over that world, and I know how I would lay my bets there, too.

        • cbolton12 hours ago
          That's using he most enthusiastic fanboy predictions as the baseline by which to judge success, not a recipe for reaching the right conclusions.

          I'd rather look at all the data available. If you want to compare to Loongson, you have to include the 20 years head start that this company has in developing microarchitectures, a big part of which can be transferred to the Loongson designs. And factor in the strategic investments in China who doesn't want to depend on ARM and x86, while in the Western world people were happy with x86 and ARM and big money is mostly flowing to AI chips, where RISC-V is successful.

          Then there is Xiangshan Kunminghu... For some reason the most powerful open source CPU is RISC-V. Chinese and not Loongson.

          • mosura11 hours ago
            > I'd rather look at all the data available

            There is no data to suggest RISCV can ever be competitive in the large core space. The longer this absence goes on (now approaching 15 years) the more evidence there is that it is structurally incapable of competitive implementations.

            If you wanted to create a project to distract a whole generation of computer architects from getting anywhere this is exactly what it would look like.

            • cbolton10 hours ago
              RISC-V was a young, purely academic project in 2011. The pivot to industry came in 2015. This was followed by announcements by companies that they were shifting to RISC-V, but guess what, it takes time. For example Western Digital announced in 2017 but shipped only in 2021.

              Now consider that RVA23 was ratified only two years ago, and the server platform specification 6 months ago! This bigger standardized base is important for larger cores, and of course these cores take longer to develop than the small ones like Western Digital's.

              I share the frustration with the lack of competitive application cores (looks like extending an ISA through open and collaborative processes takes more time than in a company). But is it not a bit early to judge the ISA's potential based on the chips on shelves today?

              Anyway large RISC-V cores do exist. The SiFive P870-D is a 6-wide core you can buy now with the BigSky SF-2U870. Ascalon (8-wide) has been available as IP for a while (though I will grant you I don't know how competitive it will be when it's finally taped out).

              Oh and the Arbel by NextSilicon (10-wide, 480-entry ROB) has been taped out. Is that large enough?

                Hopes and prayers are not a basis to judge hardware. No one will be sad about a 3rd option performant ISA, but call us when something competitive ships.

              There is also no data to suggest otherwise.

    • dragonelite13 hours ago
      It makes sense for the Chinese to make Loongson be performant, its an ISA they fully control and only have to do with domestic Loongson standard body politics instead of having to deal with global Politics in the RISC-V standard bodies.
    • imtringued14 hours ago
      Isn't it a bit hasty to say this, when one of the more powerful RISC-V CPU cores (Ascalon) hasn't been taped out yet?
      • kjs312 hours ago
        No, it's not hasty to say that a processor that I can buy and benchmark today outperforms a processor that hasn't even been taped out.

          At this point I've stopped considering TT as a serious company.

          Their original slides had Ascalon silicon in 2024 at 3ish GHz, now the devboard is supposed to be next year at 1.38GHz on an older node and it still has not taped out yet as of last month.

          • mosura7 hours ago
            Have to agree.

            One of the lessons for whatever follows RISC V is having rivals (commercial and academic) compete during spec writing before any competitive hardware is produced will doom you all to failure as everyone tries to lock everyone else into their games ahead of actually winning as a team.
