What People
are Saying
“SiFive’s RISC‑V Core IP was 1/3 the power and 1/3 the area of competing solutions, and gave FADU the flexibility we needed in optimizing our architecture to achieve these groundbreaking products.”
Jihyo Lee — CEO, FADU
“SiFive’s founders invented the RISC‑V instruction set architecture, which puts them in the driver’s seat for customers who want the benefits that open source hardware development offers.”
Drew Wingard — Sonics CTO
“SiFive’s cloud-based approach provides flexibility and ease for design teams, and we look forward to exploring its benefits.”
Raja Koduri — GM Edge Computing Solutions, Chief Architect, Intel
“RISC‑V looks as if it’s on its way to becoming a disruptive force for devices operating at the edge.”
Christine Hall — DataCenterKnowledge.com
“Like ARM processors, [SiFive’s] U540 sips power, and they already seem capable of doing the type of heavy lifting required of servers.”
Christine Hall — DataCenterKnowledge.com
“RISC‑V will allow the entire industry to realize the benefits of next-generation architectures while also enabling us to create more purpose-built devices, platforms and storage systems for Big Data and Fast Data applications.”
