What is SiFive?
SiFive is a fabless semiconductor company that designs and licenses processor intellectual property based on the open RISC-V instruction set architecture. This approach allows other companies to develop customized chips without relying on proprietary CPU architectures. Instead of manufacturing physical chips, SiFive provides highly configurable CPU core designs, system-on-chip building blocks, and supporting software tools. These solutions cater to a wide array of use cases, including data centers, artificial intelligence, automotive systems, embedded devices, and consumer electronics, positioning SiFive as a key enabler of flexible, scalable, and open-standard computing solutions within the global semiconductor ecosystem.
