SiFive secures $61m in Series E Funding

1 min read

SiFive, a leading provider of commercial RISC-V processor IP and silicon solutions, has announced it raised $61 million in a Series E round led by SK hynix, with additional funding from existing investors.

"Global demand for storage and memory from data centres is increasing as AI-powered business intelligence and data processing growth continues”, said Youjong Kang, VP of Growth Strategy, SK hynix. “SiFive is well-positioned to grow with opportunities created from data centre, enterprise, storage and networking requirements for workload-focused processor IP.”

SiFive develops a range of processor cores, accelerators, and SoC IP to create domain-specific architecture that will enable high-performance computing solutions. The company innovates by developing processor microarchitecture, SoC IP, and accelerator IP for use in workload-specific silicon. With this new investment, SiFive will be able to bring to market new products for aerospace, automotive, artificial intelligence, data centre, mobile, networking, and storage applications.

SiFive’s product portfolio of RISC-V-based microarchitectures are being used to replace and augment legacy, general-purpose proprietary architectures in workload-focused designs. 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.

“SiFive is well-positioned to capture the opportunity enabled by workload focused products,”, said Aysar Tayeb, Executive Managing Director at Prosperity7 Ventures. “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.”

Domain-specific architecture designs are further enabled by SiFive Custom Instruction Extensions (SCIE), permitting the inclusion of workload-focused IP through hardware and software optimisation. 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.
