Cambricon
Cambricon Technologies is a Beijing-based, partly state-owned fabless designer of AI accelerator chips positioned as China's leading domestic alternative to Nvidia, blacklisted by Washington in December 2022 for allegedly supporting Chinese military modernization.
Background
Cambricon, whose Chinese name Hanwuji nods to the Cambrian explosion, was spun out of the Chinese Academy of Sciences' computing institute and incorporated in March 2016. It grew from the DianNao line of academic deep-learning accelerators built by brothers Chen Tianshi and Chen Yunji, both fast-tracked PhD prodigies in computer science; Chen Tianshi remains chairman and chief executive, while his older brother returned to research soon after founding. The academy seeded the project and stayed an early shareholder, giving the firm a hybrid state-academic pedigree from the start.
Its first commercial break came in 2017, when Huawei licensed Cambricon's neural-processing technology for the Mate 10 smartphone; before 2019 Huawei accounted for the vast majority of revenue, well over ninety percent. That dependence collapsed when Huawei shifted to in-house silicon, forcing a pivot toward cloud and edge AI accelerators and government computing centers. Its core products are the MLU family and the Siyuan server chips, sold as a domestic substitute for Nvidia's data-center GPUs. On 15 December 2022 the US Commerce Department added Cambricon and several affiliates to the Entity List, citing efforts to acquire US-origin items in support of China's military modernization and cutting the fabless firm off from advanced Western tools and its foundry partner in Taiwan.
