SiFive

SiFive is a fabless semiconductor company founded in 2015 that specializes in designing processor cores and chips based on the open-source RISC-V instruction set architecture. The company provides commercial RISC-V-based platforms and custom silicon solutions, offering a range of processor core IP, development boards, and SoCs. SiFive's technology enables system designers to quickly and easily build custom chips for various applications including data centers, networking, storage, and edge computing. The company's cores offer 30-40% better power efficiency and a smaller size compared to alternatives, allowing for more cores on a chip. SiFive's online platform simplifies the process of designing and testing chips and core IP, even for those new to silicon development. In September 2020, SiFive appointed Patrick Little as President and CEO to accelerate adoption of its technology for next-generation computing solutions. As of March 2022, SiFive had a post-money valuation between USD 1-10 billion.

Key customers and partnerships

SiFive has collaborated with several high-profile organizations. In 2022, NASA announced that SiFive's RISC-V-compatible CPU cores would power its new High-Performance Spaceflight Computer, expected to deliver a 100-fold improvement in performance over its predecessor. SiFive has also worked with the Barcelona Supercomputing Center to create an open-source API for popular compilers, enabling applications to use the RISC-V Vector Extension for high-performance computing, artificial intelligence, and computer vision. The company has partnerships with major technology firms, as evidenced by its involvement in initiatives supporting RISC-V International.
