SiFive Technology


Relentless Innovation Across the SiFive IP Portfolio

SiFive is leading the RISC-V Revolution with the industry’s broadest RISC-V Core IP portfolio, from the small and efficient 2-Series, to the embedded and realtime-capable 3- and 5-Series, to the high-performance 7-Series and 8-Series, SiFive Intelligence cores for vector processing, and beyond. SiFive recognizes that it takes more than great Core IP to make our customers successful, so we make it easy to integrate, productize, and secure their SoCs by offering SiFive Shield security solutions, SiFive Insight advanced embedded trace and debug (compatible and validated with all leading 3rd party tool vendors), and world-class customer support.

SiFive Core IP Portfolio

Hardware at the Speed of Software

SiFive’s cadence of regular IP releases enables designers to plan around a predictable roadmap, with every release bringing portfolio-wide innovation configured and delivered through SiFive Core Designer. SiFive’s innovative methodology and automation enable us to innovate quickly and adapt to our portfolio of IP to customers’ and the markets’ requirements without sacrificing product maturity. In contrast, legacy IP vendors force customers to license new products for access to most new features and IP improvements.

For example, SiFive’s 20G1 Core IP release delivered significant PPA improvements across the entire SiFive Core IP portfolio, offering up to:

  • 2.8x more performance
  • 25% lower power
  • 11% smaller area

The 20G1 release also introduced new pre-integrated SiFive Insight advanced trace and debug capabilities along with broad ecosystem support as well as SiFive’s unique compatibility with Arm® CoreSight™technology to maximize ease of integration into existing SoC architectures..

The SiFive 20G1 6.0 Update builds on the improvements in the 20G1 release to enhance the capabilities of the 7-Series by further increasing performance and efficiency and adding features.
