SiFive

SiFive is a semiconductor IP company founded in 2015 and headquartered in San Mateo, California, by co-creators of the open RISC-V instruction set architecture. It addresses the need for customizable, licensable processor cores as an alternative to closed proprietary CPU architectures for chip designers building AI, automotive, edge and data center silicon.

The company licenses a portfolio of RISC-V processor core IP grouped into Essential, Performance, Intelligence and Automotive product lines, together with system IP such as debug/trace and security modules, and design tools including Core Designer and Freedom Studio. Customers are semiconductor and systems companies that integrate SiFive cores into their own chips for IoT, automotive ADAS, storage and datacenter accelerators.

1. RISC-V core families: Essential, Performance, Intelligence and Automotive processor IP lines for different power and performance targets.

2. Core Designer: configuration platform to customize and generate RISC-V cores for a target design.

3. System IP: Insight trace/debug, IOMMU and WorldGuard security modules for integration alongside cores.

4. Software stack: Freedom Studio and Freedom SDK toolchains for firmware development on SiFive-based chips.

5. Reference platforms: HiFive and BigSky boards for early software bring-up before silicon is ready.

6. Multi-market licensing: cores tailored for AI/ML, automotive, edge and datacenter chip programs.
