Semiconductor Update: China’s RISC-V Ecosystem Developments — Key Takeaways

China’s RISC-V ecosystem has reached a critical inflection point in early 2025, with over 300 domestic enterprises now actively engaged in RISC-V-based chip design — a 40% increase from 2023. This open-source instruction set architecture, known as RISC-V 开源指令集架构 (kāiyuán zhǐlìng jí jiàgòu), is rapidly becoming a cornerstone of China’s semiconductor self-sufficiency strategy. It offers a licensing-free alternative to proprietary architectures like ARM and x86, allowing Chinese firms to bypass geopolitical export controls and licensing restrictions — a key motivator amid ongoing US-China tech tensions.

The following numbers put the scale into context:

• China’s RISC-V chip market is projected to grow from $540 million in 2024 to $2.1 billion by 2028, a compound annual growth rate of 31% (IDC estimates).
• In 2024, China accounted for 45% of all global RISC-V chip tape-outs, up from 32% in 2022.
• Alibaba’s T-Head Semiconductor has released more than 10 XuanTie processor cores, with cumulative shipments surpassing 4 billion units as of early 2025.
• The Chinese central government has allocated at least ¥50 billion (~$7 billion) for RISC-V research and ecosystem development through 2027 under the “RISC-V Strategic Initiative.”
• RISC-V International membership from China exceeded 150 organizations in 2024, a 60% year-over-year jump, giving the country significant influence over future standard extensions.

Government Policy and Investment Accelerating RISC-V Adoption

Beijing has made RISC-V a pillar of its semiconductor self-reliance roadmap. In late 2024, the Ministry of Industry and Information Technology published a white paper explicitly encouraging RISC-V adoption in IoT, AI edge devices, and embedded systems. The document set a target: 50% of new IoT chip designs in China will use RISC-V by 2026.

Provincial governments are following suit. The Shanghai Municipal Science and Technology Commission launched a ¥5 billion RISC-V innovation fund in early 2025, aimed at subsidizing tape-outs and toolchain development. Meanwhile, the China RISC-V Alliance, which now counts over 300 corporate and academic members, has released a set of “Recommended RISC-V Profiles” to promote interoperability across domestic designs. These profiles are distinct from the international RISC-V ratified standards, raising questions about potential fragmentation.

The policy push is also visible in education. More than 60 Chinese universities now offer RISC-V-focused courses, and the government has sponsored the development of open-source EDA tools tailored to RISC-V flows. This talent pipeline is expected to produce thousands of skilled RISC-V engineers annually by 2027.

Major Chinese Tech Companies Leading the Charge

The most prominent player remains Alibaba’s T-Head Semiconductor, whose XuanTie (玄铁, xuán tiě) processor family spans from ultra-low-power microcontroller cores to the high-performance C910 and C920 series. T-Head has open-sourced several core models, allowing third parties to modify and integrate them. In 2024, the company announced that XuanTie cores had been used in over 4 billion chips across smartphones, smart home devices, industrial controllers, and cloud servers.

Huawei, despite US sanctions limiting its access to ARM’s newest designs, has quietly accelerated its RISC-V work. Its HiSilicon subsidiary has developed a RISC-V-based AI accelerator for edge inference, currently deployed in surveillance cameras and smart retail systems. While Huawei has not publicly disclosed RISC-V chip volumes, industry sources estimate over 100 million HiSilicon RISC-V SoCs shipped in 2024 alone.

Other major companies are joining in:

• Tencent has invested in StarFive and SiFive China to develop custom RISC-V chips for its data centers and gaming servers.
• Baidu announced a RISC-V-based AI inference processor aimed at autonomous driving platforms, with production expected in 2026.
• State-owned chipmaker UNISOC has integrated a RISC-V coprocessor into its latest 5G IoT modem lineup.

The ecosystem is further supported by a growing number of domestic EDA and IP providers. Companies like Synopsys China and Cadence have expanded their RISC-V verification solutions, but homegrown firms such as X-Inc and Corigine are gaining market share with tailored RISC-V toolchains.

Challenges and Strategic Implications for Foreign Executives

Despite the momentum, China’s RISC-V ecosystem faces significant hurdles. Software compatibility is the most critical bottleneck. While the Linux kernel and several RTOSes support RISC-V, the application ecosystem — especially for mobile and desktop environments — lags far behind ARM and x86. Chinese RISC-V chips currently cover only 15% of the performance range needed for high-end server workloads, though that gap is narrowing with newer designs targeting cloud and edge AI.

Fragmentation risk is another concern. China’s push for “localized” RISC-V profiles could lead to two separate standards: one driven by RISC-V International and another by Chinese entities. This would complicate software portability and raise costs for foreign firms trying to serve both markets. Executives should monitor whether Chinese RISC-V extensions remain compatible with global profiles or diverge over time.

For foreign semiconductor companies, the rise of Chinese RISC-V presents both a threat and an opportunity. On one hand, it could erode the market for ARM licensees and x86 suppliers inside China, particularly in IoT, MCU, and low-power segments. On the other hand, it opens avenues for collaboration, such as providing RISC-V IP licensing, design services, or advanced manufacturing support to Chinese ecosystem partners.

Geopolitical factors add complexity. The US government has so far refrained from restricting RISC-V technology, but pressure to limit Chinese access to RISC-V International decision-making is rising. Should export controls expand to cover RISC-V tools or cores, China’s domestic ecosystem could become more insular — further accelerating its drive for self-sufficiency.

NEXT STEPS: Three Decision-Path Recommendations for Foreign Executives

1. Assess your exposure to Chinese RISC-V alternatives
   Evaluate which product lines in your portfolio could face competition from Chinese RISC-V chips in the next 2–3 years. Prioritize segments where performance requirements match the current capabilities of Chinese RISC-V cores (IoT, edge AI, embedded control). Plan for potential market share erosion and adjust pricing or partnership strategies accordingly.
2. Explore co-development and licensing opportunities
   Chinese companies are hungry for proven RISC-V IP, verification tools, and software stacks. Consider offering your RISC-V IP cores or design services to Chinese partners through joint ventures or licensing agreements. This can generate revenue while building influence over Chinese standards development — helping prevent fragmentation.
3. Monitor China’s RISC-V standards divergence closely
   Appoint a team to track the evolution of the China RISC-V Alliance’s recommended profiles and compare them with RISC-V International ratified standards. If divergence widens, prepare a dual-standard strategy — maintain a compatible core for the global market and a separate optimized variant for the Chinese market. Engage with RISC-V International to ensure your voice is heard in shaping future extensions.
