Huawei’s New Kirin Chip Designed to Bypass US Sanctions

Huawei is changing how it builds microchips to bypass ongoing U.S. trade restrictions. At a major tech conference in Shanghai, the Chinese tech giant unveiled a new chip design method that does not rely on machines blocked by the U.S. sanctions (via Nikkei Asia).

Instead of focusing solely on making components physically smaller, Huawei is redesigning how data flows inside the chip to boost speed and power. The company announced that its upcoming Kirin smartphone processor, scheduled to launch in flagship phones later this year, will be the first to feature this new design.

For years, Washington has blocked Huawei from buying advanced chipmaking equipment, like the extreme ultraviolet lithography machines made by Dutch firm ASML. This made it incredibly difficult for Huawei’s chip division, HiSilicon, to compete with Western tech giants who have access to the latest factory tech.

To survive, Huawei had to find a creative workaround. At the IEEE International Symposium on Circuits and Systems, He Tingbo, the president of HiSilicon, introduced a concept the company calls the Tau Scaling Law.

Traditional chip design relies on “Moore’s Law,” which means shrinking physical transistors every couple of years to pack more power into a tiny space. Huawei’s new approach focuses instead on “time scaling.” By rearranging internal wiring to dramatically shorten the time it takes for electronic signals to travel, they can achieve massive performance gains without needing smaller parts.

Huawei calls the specific technology behind this LogicFolding. The upcoming 2026 Kirin chip will use this architecture to increase transistor density by 53.5 per cent, which allows it to match the efficiency of chips built on more advanced Western production lines. Huawei reports that the chip’s core performance has jumped by 41% compared to the previous generation.

Looking even further ahead, Huawei claims this design shift will allow them to design chips with a transistor density equivalent to a cutting-edge 1.4-nanometre process by 2031.
