Since its birth in 2010, the RISC-V open instruction set architecture has made the critical leap from academic research to industrial deployment. In 2026, RISC-V ecosystem development has entered an accelerated phase: global RISC-V International membership exceeds 4,000, and members of the China RISC-V Industry Alliance surpass 800, covering the full-stack ecosystem of chip design, EDA tools, operating systems, and application software.
Unlike the closed licensing models of Arm and x86, RISC-V’s openness allows any organization to extend custom functionality based on the standard instruction set, which is especially important against a backdrop of geopolitical uncertainty in chip architecture licensing. Chinese chip vendors are actively embracing RISC-V as a strategic path to reduce dependence on Arm.

MCU Field: RISC-V Replacing Cortex-M
In the MCU field, RISC-V’s substitution for the Arm Cortex-M series is most pronounced. Domestic RISC-V MCUs such as GigaDevice’s GD32VF series, WCH’s CH32V series, and HXS’s HX2000 series have entered mass production, covering full scenarios from low-cost 8-bit replacements to high-performance 32-bit applications.
The core advantage of RISC-V MCUs lies in their modular instruction-set design, which allows vendors to tailor and extend based on target scenarios, avoiding the “paying for unused features” problem in Arm licensing. For example, an IoT scenario only needs the RV32IC base instructions plus custom low-power extensions, without paying the full Cortex-M4 licensing fee.
| Feature | Arm Cortex-M | RISC-V RV32 |
|---|---|---|
| Licensing Model | Paid license, fixed IP | Open-source free, customizable extensions |
| Instruction Set Extensions | Defined by Arm, not modifiable | Standard base + custom extensions |
| Ecosystem Maturity | Very mature, complete toolchain | Growing rapidly, GCC/LLVM support |
| Power Optimization | Depends on Arm low-power IP | Trimmable instructions reduce power |
| Cost | License fee + royalty | Zero license fee, design cost only |
AI Accelerators: RISC-V’s New Battlefield
AI inference accelerators are the most imaginative application direction for RISC-V. StarFive’s JH8200 integrates RISC-V CPU cores with a self-developed NPU, delivering 4 TOPS of edge AI inference compute. Alibaba’s T-Head Xuanying 1520 adopts RISC-V + self-developed XuanTie AI extensions, running mainstream AI frameworks in a Linux environment.
RISC-V’s unique value in AI chips lies in its custom vector extensions (RVV) and AI-specific extensions, which can optimize data flow for inference scenarios and are more efficient than general-purpose GPU architectures. SiFive’s P870 core supports the RVV 1.0 vector extension, improving energy efficiency by over 30% compared to equivalent Arm cores in AI inference tasks.
Automotive Electronics: Breaking Through Safety Levels
The G-K01 chip is the world’s first 6-core RISC-V chip that meets the ASIL-D functional safety level, marking a breakthrough for RISC-V in automotive electronics. The chip adopts a lockstep dual-core + watchdog + safety island architecture, meeting the highest safety level requirements of ISO 26262, and can be used in critical systems such as drive-by-wire chassis and active safety.
RISC-V’s development path in automotive chips is clear: start with auxiliary cores in domain controllers, then gradually upgrade to main control cores. Several automotive-grade chip vendors have launched RISC-V projects, and the first mass-produced vehicles with RISC-V main controllers are expected around 2028.
The rise of the RISC-V ecosystem is reshaping the global chip architecture landscape. From MCU substitution to AI acceleration to automotive-grade breakthroughs, RISC-V is no longer just an “academic toy” but a third-pillar architecture with real industrial competitiveness. Honchak Electronics will continue to track RISC-V chip product developments and provide customers with the latest selection information.
