In a pivotal move for the semiconductor industry, RISC-V International has secured approval as a Publicly Available Specification (PAS) Submitter from the ISO/IEC Joint Technical Committee 1 (JTC1), marking the first step toward international standardization of the open-source instruction set architecture (ISA). Announced at the RISC-V Summit North America 2025, this development positions RISC-V as a potential game-changer in global chip design, challenging proprietary giants like Arm and x86.

The approval, revealed by Andrea Gallo, CEO of RISC-V International, and Phil Wennblom, Chair of ISO/IEC JTC1, underscores the growing momentum behind RISC-V. ‘RISC-V is an industry standard, like USB or Wi-Fi,’ Gallo stated in the announcement, emphasizing its open, collaborative nature. This status allows RISC-V to submit specifications directly to ISO for ratification, a privilege no other ISA has achieved, according to RISC-V International.

The Path to PAS Submitter Status

The journey to this milestone involved rigorous evaluation by JTC1, which recognizes organizations capable of producing high-quality, consensus-driven standards. RISC-V’s model, governed by its members through transparent voting, aligns perfectly with ISO’s requirements. As detailed in reports from Lemmy, this ensures updates to the RISC-V ISA occur without disrupting existing designs, fostering ecosystem-wide innovation.

Industry observers note that this step addresses a key barrier: formal international recognition. While RISC-V specifications have been publicly available under Creative Commons licenses for years, ISO endorsement could accelerate adoption in regulated sectors like automotive and aerospace, where standardized compliance is crucial.

Broader Implications for Semiconductor Innovation

Beyond standardization, this approval signals RISC-V’s maturation amid geopolitical tensions in chip manufacturing. Posts on X highlight China’s strategic pivot to RISC-V to bypass Western restrictions, with users like Inter Arma Enim Silent Leges predicting it will ‘leapfrog the West’ by preventing monopolies. This aligns with news from All About Circuits, which reported on RISC-V’s leadership changes and hardware outpouring in 2025.

Recent advancements include NVIDIA’s announcement at RISC-V Summit China 2025 that CUDA is coming to RISC-V, enabling it as a main processor in AI systems, as shared in X posts from RISC-V International. This could democratize high-performance computing, making advanced AI accessible without proprietary dependencies.

RISC-V’s Ecosystem Expansion in 2025

The year 2025 has seen explosive growth in RISC-V hardware. Benchmarks of single-board computers (SBCs) like the Orange Pi RV2 and Milk-V Jupiter, as tested by Explaining Computers and discussed on X, reveal strides in performance and efficiency. Meanwhile, Intel’s ongoing investments, dating back to 2022 but reinforced in current updates from RISC-V International, underscore cross-industry collaboration.

Software ports are equally vital. A new course on porting software to RISC-V (LFD 114), announced by RISC-V International, aims to bridge gaps in developer tools. Additionally, progress in Chromium V8 for RISC-V, presented by maintainer Qiu Ji at recent events, promises better web performance on RISC-V platforms, per X updates from Daniel Bovensiepen.

Challenges Amid Rapid Adoption

Despite these wins, challenges persist. Geopolitical risks, such as U.S. export controls, have fueled RISC-V’s appeal in Asia, but they also raise concerns about fragmentation. S.L. Kanthan’s 2023 X post, still relevant in 2025 discussions, warned that Western sanctions are ‘digging the grave for its own technology’ by pushing decoupling from Intel and Arm.

Technical hurdles remain, including maturing vector extensions for AI workloads. EDN: Voice of the Engineer recently noted RISC-V’s readiness to ‘raise the game in AI,’ but full ecosystem parity with established ISAs will take time. Ratification of the RVA23 Profile Standard in October 2024, as per RISC-V International, lays groundwork for consistent implementations.

Industry Voices and Future Trajectories

Experts like Frans Sijstermans from NVIDIA, speaking at RISC-V Summit China, highlighted RISC-V’s modularity as key to its extensibility. Google’s choice of RISC-V for its Coral NPU, as explained by Billy Rutledge: ‘We’ve chosen RISC-V because of its rapid adoption and interest in the ecosystem today, but also it’s modular and flexible,’ per X posts from RISC-V International.

Looking ahead, ISO standardization could open doors to critical infrastructure applications. Updates from XCP-ng on Xen hypervisor for RISC-V indicate progress in virtualization, essential for cloud and data centers. With over 13 billion RISC-V cores shipped by mid-2025, per industry estimates, the architecture is no longer niche.

Global Standardization’s Ripple Effects

The PAS Submitter status isn’t just symbolic; it streamlines the path to full ISO standards, potentially integrating RISC-V into international trade agreements. As Phil Wennblom emphasized at the summit, this impartial recognition from a trusted body like JTC1 validates RISC-V’s collaborative ethos.

Comparisons to other standards abound. Just as USB unified peripherals, RISC-V could standardize processor design, reducing costs and spurring innovation. Recent X sentiment, including from 포시포시 on VLSI advancements, ties RISC-V to broader trends like Intel’s 18A process, suggesting hybrid futures where open ISAs complement proprietary tech.

Economic and Strategic Shifts

Economically, this milestone could reshape supply chains. China’s coordination around RISC-V, as noted in X posts, aims for semiconductor independence. In Europe, calls for national strategies, like those from Ger Mann on X, urge adoption to counter U.S. and Asian dominance.

For startups, the open nature lowers barriers. Honors from RISC-V International in 2022, still celebrated in 2025 blogs, recognized contributions that built this foundation. As Andrea Gallo reflected in RISC-V International, the model’s transparency ensures longevity.

Navigating the Road Ahead

While optimism abounds, stakeholders must address interoperability. The RISC-V Summit China 2025 reflections, shared via RISC-V International, highlight software contributors’ roles in smoothing adoption pains.

Ultimately, this ISO approval cements RISC-V’s trajectory from academic curiosity to industrial powerhouse, with 2025 marking a year of milestones that could redefine computing’s open future.
