A Winning Processor Portfolio.

The SiFive® Core IP portfolio is comprised of three distinct families spanning from high-performance application processors to area-optimized, low-power embedded 64- and 32-bit microcontrollers, to vector processors designed with modern compute requirements in mind. All SiFive processors are based upon the RISC-V ISA.

The SiFive Essential™ family gives you the freedom to start with a standard, pre-defined core, or to employ SiFive Core Designer to build your own processor configuration. SiFive Performance™ processors deliver unparalleled performance in an energy-efficient small footprint, and the SiFive Intelligence™ Family leverages a software-first approach to processor design to address the future requirements of deploying machine learning technology to the edge with high performance vector compute capability.

Get started today and discover our complete, scalable portfolio of RISC-V cores for designers targeting all markets, who are at the vanguard of SoC design and are dissatisfied with the status quo.
