Today, as the semiconductor industry undergoes sweeping consolidation, geopolitical realignments, and an unprecedented surge in AI-driven computing demands, RISC-V is rapidly gaining traction—backed by some of the world’s most influential chipmakers.

RISC-V: From Academic Origins To A Billion-Core Milestone

Conceived in 2010 at UC Berkeley, RISC-V was built from the ground up as a royalty-free, open instruction set architecture (ISA), designed for modern workloads and easy extensibility. Spearheaded by a team that remains deeply involved through RISC-V International (RVI), the project aimed to foster an open hardware ecosystem that could spark innovation across both academic and industrial domains.

This vision has gained powerful momentum. In 2024, Nvidia shipped over one billion RISC-V cores embedded within its GPUs. These cores function as microcontrollers and security processors, handling critical tasks such as power management, telemetry, and safety monitoring—areas where compact, customizable architectures shine. This milestone was not an isolated achievement but part of a broader validation of RISC-V’s capabilities.

Just days ago, Nvidia made another groundbreaking announcement: CUDA support is coming to RISC-V host processors. This means developers will soon be able to build GPU-accelerated applications directly on RISC-V CPUs—an enormous leap forward. It transforms RISC-V from a niche controller architecture into a credible general-purpose compute platform, especially for heterogeneous AI systems in embedded, edge, and autonomous environments—spaces previously dominated by Arm.

For a leader like Nvidia in accelerated computing to endorse RISC-V as a CUDA host marks a pivotal shift. It signals strong confidence in RISC-V’s future in client devices and data centers, and acts as a catalyst for wider industry adoption.

SiFive: From RISC-V Pioneers To Leading IP Powerhouse

Few companies have been as instrumental in bringing RISC-V to market as SiFive. Founded by three of the original architects of the ISA, SiFive has evolved into a premier provider of RISC-V intellectual property (IP), offering processor cores ranging from ultra-low-power MCUs to high-performance vector and application-class CPUs.

Its technology is already integrated into systems used by major cloud and AI firms. SiFive continues to expand its reach—recently partnering with Synopsys to simplify SoC design using standard EDA tools. Meanwhile, support from Red Hat and Canonical ensures seamless Linux integration. There are also reports that Google is incorporating SiFive cores into next-generation TPU designs, further solidifying SiFive’s position as a top-tier RISC-V partner.

Internally, SiFive has broadened its scope to include defense, aerospace, automotive, and edge AI—sectors where deterministic performance, vector processing for imaging and AI, and architectural flexibility are essential.

The RISC-V Ecosystem Gains Momentum

A robust ISA requires a thriving ecosystem, and RISC-V is now seeing strong support across the full technology stack. Android is being actively ported to RISC-V, with full compliance to the RVA23 specification in progress. Ubuntu and Red Hat Enterprise Linux already run on SiFive-based hardware, giving developers access to familiar development environments and tools.

Tenstorrent, an AI chip startup co-founded by renowned architect Jim Keller and a SiFive customer, is building RISC-V-based CPUs for AI and high-performance edge computing. Another emerging player, Ahead Computing—founded by ex-Intel engineers—is making quiet but significant advances in server-grade RISC-V processors.

Moreover, all seven of the so-called “Magnificent Seven” tech giants are reportedly leveraging RISC-V in some form, with five actively collaborating with SiFive (and likely other vendors). Use cases span datacenter management processors, AI accelerators, and custom embedded cores—demonstrating RISC-V’s versatility across diverse applications.

Customization And The Rise Of Chip Sovereignty

What sets RISC-V apart isn’t just its open license—it’s the freedom to customize. Unlike x86 and Arm, which enforce rigid instruction sets and restrictive licensing models, RISC-V empowers chip designers to build exactly what they need, eliminating unnecessary overhead.

This is a game-changer in the AI era, where diverse models and complex workloads demand domain-specific, energy-efficient hardware.

Equally important is the geopolitical dimension. As nations strive to secure independent semiconductor supply chains, RISC-V has emerged as a strategic tool for technological sovereignty. In the U.S., Department of Defense initiatives are increasingly adopting open ISAs to reduce dependence on foreign-controlled IP. Even GlobalFoundries’ acquisition of MIPS reinforces the RISC-V trend—broadening its IP portfolio while sidestepping direct competition.

Looking Ahead: RISC-V’s Promise, Hurdles, And Path Forward

Despite its growing momentum, RISC-V still faces challenges. The software ecosystem, while improving fast, lacks the decades of optimization found in x86 and Arm. Fragmented toolchains, sparse driver support, and immature debugging tools remain obstacles—especially in high-performance computing.

Governance is another concern. Although RISC-V International works diligently to standardize extensions and maintain compatibility, the risk of fragmentation looms if vendors stray too far from the baseline specification.

Still, the advantages are compelling. In an industry moving toward domain-specific architectures, chiplet-based designs, and heterogeneous computing, RISC-V delivers unmatched flexibility, openness, and modularity.

RISC-V won’t replace Arm or x86 overnight—and it doesn’t need to. Instead, it’s establishing strong footholds in markets where customization, efficiency, and freedom from licensing restrictions provide real competitive edges.

As companies like Nvidia, Google, Red Hat, and others adopt RISC-V not just for microcontrollers but for host computing, AI pipelines, and full-stack development, the architecture is evolving from an alternative to a strategic imperative.

In a semiconductor world often constrained by proprietary IP and licensing barriers, RISC-V offers a different future—one that’s open, adaptable, and increasingly impossible to overlook.
