We invented RISC-V
SiFive was founded by the inventors of RISC-V, who have been developing the RISC-V instruction Set Architecture (ISA) since 2010. Focused on RISC-V solutions, we maintain the largest investment and team focused on RISC-V, delivering the broadest portfolio of RISC-V products that is the most widely adopted in the world.
RISC‑V is a free and open ISA designed for today’s software stacks. Rapid industry-wide adoption has enabled RISC‑V to be the new compute standard.
It’s time to specialize
SiFive innovation in microarchitecture design and configurability has created an industry-leading portfolio of RISC-V processor cores for domain-specific SoC design. Taking full advantage of leading process technology requires lean, workload-tuned silicon that can be agilely developed based on open standards with industry-led and individual customizations.
The SiFive Core IP portfolio of RISC-V processor cores delivers this based on unique microarchitecture generators that offer unmatched configurability and extensibility.
Configure your RISC-V core
SiFive Cores are the most silicon-deployed RISC‑V solutions in the world. From low-power embedded microcontrollers to multi-core application processors, our core IP is the lowest risk, easiest path to RISC-V silicon.
SiFive Cores are configurable and can be tuned to meet precise needs with SiFive Core Designer the award winning web-based configuration tool for SiFive Core IP.
Free evaluation Dev Kits with Verilog RTL and FPGA bitstreams are available to download now.
Here’s how it works
Configure a SiFive Core to meet the precise needs of your product.
Simulate with fully-functional, synthesizable Verilog RTL. Run your application code on an FPGA. Work with our application team for guidance.
Licensing is straightforward, and access to your unrestricted RISC-V core IP is available quickly.
