SiFive, a San Francisco, CA-based provider of customized, open-source-enabled semiconductors, raised $8.5m in a Series B funding round.
The round was led by Spark Capital with participation from Osage University Partners and existing investor Sutter Hill Ventures. In conjunction with the funding, Todd Dagres, general partner at Spark Capital, will join SiFive’s board of directors.
The company has raised $13.5m in total funding to date.
Co-founded by RISC-V inventors Krste Asanovic, Yunsup Lee and Andrew Waterman, SiFive provides customized semiconductors based on the free and open RISC-V instruction set architecture. In its first six months of availability, more than 1,000 HiFive1 software development boards have been purchased and delivered to developers in over 40 countries. Additionally, the company has engaged with multiple customers across its IP and SoC products, started shipping the RISC-V SoC in November 2016 and announced the availability of its Coreplex RISC-V based IP earlier this month.
SiFive, which maintains a toolchain, SDK and BSPs with binaries of the latest open source tools, including OpenOCD, GNU Debugger, Arduino IDE and the Eclipse integrated development environment, recently launched its Coreplex IP and announced a growing ecosystem of partners, including Faraday, Microsemi and United Design Systems.
