It’s time to specialize...
The future is domain-specific.
SiFive innovation in microarchitecture design and configurability has created an industry-leading portfolio of RISC-V processor cores for domain-specific architecture. Taking full advantage of leading process technology requires lean, workload-tuned silicon that can be agilely developed based on open standards with industry-led customizations and individual customizations. The SiFive Core IP portfolio of RISC-V processor cores delivers this based on four unique microarchitecture generators that offer unmatched configurability, extensibility, and customization.
We invented RISC‑V.
SiFive’s founders are the same UC Berkeley professor and PhDs who invented and have been developing the RISC‑V Instruction Set Architecture (ISA) since 2010.
RISC‑V is a free and open ISA designed for today’s software stacks. Rapid industry-wide adoption has poised RISC‑V to be the new standard for compute.
Customize your RISC-V core.
SiFive Standard Cores are the most silicon-deployed RISC‑V solutions in the world. From low-power embedded microcontrollers to multi-core applications processors, our core IP is the lowest risk, easiest path to RISC-V.
SiFive Standard Cores are customizable and can be tuned to meet precise needs with the SiFive Core Designer.
Free evaluation Dev Kits with Verilog RTL and FPGA bitstreams are available to download now.
Here's how it works.
Customize a SiFive Standard Core to meet the precise needs of your product.
Simulate with fully-functional, synthesizable Verilog RTL. Run your application code on an FPGA.
Licensing is straightforward and your custom RISC-V core IP is available within weeks.
“RISC‑V offers a fresh approach that has the potential to help reduce SoC development time and cost significantly.”
