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 application processors, our core IP is the lowest risk, easiest path to RISC-V.
SiFive Cores Series are customizable and can be tuned to meet your precise needs with the SiFive Core Designer. SiFive Standard Cores are pre-configured design points in a Core Series and are perfect starting points.
E Cores are 32-bit embedded cores addressing the MCU, edge computing, AI and IoT markets. 2 Series E Cores are power and area optimized: 2–3-stage, single-issue pipeline, as small as 13.5k gates 3 and 5 Series E Cores are efficient and performance oriented: 5–6-stage, single-issue pipeline 7 Series E Cores are the highest performance: 8-stage, dual-issue superscalar pipeline.
