RISC-V core IP, available now.
SiFive RISC-V core IP are the most silicon-deployed RISC‑V solutions in the world. From low-power embedded microcontrollers (as small as 13.5k gates) to multi-core applications processors, our core IP is the lowest risk, easiest path to RISC-V.
SiFive Cores Series are customizable and can be tuned to meet precise needs with the SiFive Core Designer. SiFive Standard Cores are pre-configured design points in a Core Series and are perfect starting points.
