Despite initial skepticism regarding the independent development of Xiaomi's Xuanjie O1 chip, both Xiaomi's official statement and Arm's website have confirmed its status as a Xiaomi self-developed chip. Leveraging the Armv9.2 architecture, the chip boasts system-level design and backend optimization carried out by Xiaomi's team, utilizing a cutting-edge 3nm process. Zhu Dan, Xiaomi's Vice President, clarified that the chip is based on Arm IP soft core authorization, with Xiaomi independently completing the internal architecture design. Industry experts opine that companies often embark on independent research and development from public versions, and Xiaomi's progress in this regard merits serious attention.
