  • SiFive — a leading provider of commercial RISC-V processor IP and silicon solutions — announced it raised $61 million in Series E funding

SiFive — a leading provider of commercial RISC-V processor IP and silicon solutions — announced it raised $61 million in Series E funding led by SK hynix and the company was joined by new investor Prosperity7 Ventures with additional funding from existing investors Sutter Hill Ventures, Western Digital Capital, Qualcomm Ventures, Intel Capital, Osage University Partners, and Spark Capital.

SiFive develops a range of processor cores, accelerators, and SoC IP to create domain-specific architecture that will enable efficient, high-performance computing solutions. And SiFive innovates by developing processor microarchitecture, SoC IP, and accelerator IP for use in workload-specific silicon.

With this funding round, SiFive will help leading semiconductor companies bring to market new products for aerospace, automotive, artificial intelligence, data center, mobile, networking, and storage applications.

SiFive’s product portfolio of RISC-V-based microarchitectures is the perfect choice to replace and augment legacy, general-purpose proprietary architectures in workload-focused designs. And recently, SiFive announced the SiFive 20G1 update for SiFive Core IP, enabling significant enhancements for performance, power, area, and features with pre-integrated SiFive Shield for whole SoC security and SiFive Insight advanced trace and debug capabilities.

The domain-specific architecture designs are further enabled by SiFive Custom Instruction Extensions (SCIE), permitting the inclusion of workload-focused IP through hardware and software optimization. And SiFive heterogeneous architecture allows the integration of mixed processor core designs in a coherent cluster for scale-out problems, leveraging SCIE to accelerate workload processing in an efficient manner.


“We are very pleased by the new and renewed investment in the SiFive vision and mission. SiFive’s winning product portfolio will continue to expand and be adopted for solutions that require domain-specific architectures.”

— Dr. Naveed Sherwani, Chairman, President, and CEO of SiFive

“Global demand for storage and memory in the data center is increasing as AI-powered business intelligence and data processing growth continues. SiFive is well-positioned to grow with opportunities created from data center, enterprise, storage and networking requirements for workload-focused processor IP.”

— Youjong Kang, VP of Growth Strategy, SK hynix

“SiFive is well-positioned to capture the opportunity enabled by workload focused products. We’re pleased to be part of the global shift to workload-focused designs, and believe SiFive’s domain-specific architecture IP will fuel innovation and solutions for computing challenges we see today.”

— Aysar Tayeb, Executive Managing Director at Prosperity7 Ventures
