We Help Drive the Global Ecosystem

By supporting the open standard RISC-V architecture, the last ISA that will ever matter, SiFive helps spur innovation across a broad community of thousands while also ensuring our customers benefit from the high-performance evolution of our IP, ecosystem, extensions, and tools.

Focused on Your Success

Our unwavering commitment to superior products and customer support allows you to maximize innovation and differentiation with confidence.

Our Quality Policy

SiFive’s mission is to create the best computing solutions in the world to enable our customers to deliver differentiated, best-in-class products in the markets they serve. Our focus is on providing product excellence, predictable execution, and outstanding customer support. We comply with commitments to our customers, requirements of regulatory agencies, and our own business processes. We are committed to continually improving our products, services, and our business processes.

A true U.S. innovation success story, we were founded in the Silicon Valley, by the inventors of RISC-V. More than 350 design wins attest to our ability to meet previously unachievable performance, power, and area target combinations for today’s most challenging workloads. For some applications, SiFive cores deliver comparable performance to equivalent Arm cores with much lower power consumption in a smaller area. Best of all, they give you total control of design, build, and everything else. > 2 Billion devices benefit from chips built with SiFive IP.

Customers choose RISC-V because:

  • It’s a modern architecture for today’s workloads
  • Designers can adapt the open standard ISA for their specific needs on Microsoft or Linux systems
  • No vendor lock-in and flexible and portable software
  • The ISA evolves with customer requirements
  • Provides superior compute density in terms of performance per watt

SiFive is at the forefront of RISC-V, partnering with some of the world’s largest semiconductor manufacturers, global hyperscale data centers, and leading consumer device companies.

Based on this collaboration, we deliver the CPU architecture you need to innovate faster as you develop wearables, automotive and aerospace technology, and other consumer devices. Here’s just some of what SiFive delivers:

  • Innovative RISC-V CPU IP for the semiconductor industry
  • Development of application-specific silicon faster than ever
  • The full potential of the open RISC-V architecture, unleashed at scale
