Huawei's 'chip queen' He Tingbo unveils Tau Scaling Law at Shanghai symposium

On Monday, at the IEEE International Symposium on Circuits and Systems held in Shanghai, He Tingbo, known as Huawei's 'chip queen', introduced the Tau (τ) Scaling Law. This framework suggests enhancing chip performance by minimizing delays throughout devices, circuits, chips, and computing systems, instead of depending solely on the geometric scaling of transistors. As Moore's Law begins to falter, this strategy aims to steer chip development. He drew parallels with the ancient Dujiangyan irrigation system in Sichuan and interpreted US sanctions as engineering challenges. The presentation emphasizes Huawei's potential for innovation rather than its limited access to cutting-edge chipmaking technologies.
