Huawei's Kirin line of chips is designed and developed by Huawei's HiSilicon unit. Although Huawei claims that the Kirin chip is self-developed, the Kirin chip design may use some third-party technologies and licenses, such as ARM architecture or other technologies. In addition, hisilicon also works with other partners, including foundries. Therefore, although Huawei has the capability of independent research and development and design, the research and development of Kirin chips may also be affected by some external technologies and cooperation.
