Huawei's top semiconductor scientist, Liao Heng, recently appeared on a four-hour-long interview where he discussed the best path forward in chip design, addressed some of the hardships Huawei faced when US sanctions cut it off from global chipmaking suppliers, and lauded Huawei's novel Tau Scaling Law approach. The appearance was a signal of confidence from the company. Huawei's Tau Scaling Law proposes focusing on improving transmission speeds between parts in a computer system. The company is set to soon unveil its first smartphone chip designed under that framework.
