HiSilicon

HiSilicon (Chinese: 海思; pinyin: Hǎisī) is a Chinese fabless semiconductor company based in Shenzhen, Guangdong province and wholly owned by Huawei. HiSilicon purchases licenses for CPU designs from ARM Holdings, including the ARM Cortex-A9 MPCore, ARM Cortex-M3, ARM Cortex-A7 MPCore, ARM Cortex-A15 MPCore,^[2][3] ARM Cortex-A53, ARM Cortex-A57 and also for their Mali graphics cores.^[4][5] HiSilicon has also purchased licenses from Vivante Corporation for their GC4000 graphics core.

HiSilicon is reputed to be the largest domestic designer of integrated circuits in China.^[6] In 2020, the United States instituted rules that require any American firms providing equipment to HiSilicon or non-American firms who use American technologies or IPR (such as TSMC) that supply HiSilicon to have licenses^[7] as part of the ongoing trade dispute, and Huawei announced it will stop producing its Kirin chipsets from 15 September 2020 onwards^[8] due to this disruption of its supply chain. On August 29, 2023, Huawei announced the first fully domestically fabricated chip, the Kirin 9000S, which is used on its latest Mate 60 Pro phablet series of phones and MatePad 13.2 tablets.

History

HiSilicon was Huawei's ASIC design center, which was founded in 1991.

• 2004– Shenzhen HiSilicon Semiconductor Co., Ltd. was registered and the company was formally established.
• 2016– HiSilicon's Kirin 960 chipset was rated one of the "best of Android 2016" in performance by Android Authority.^[9]
• 2019– Shanghai HiSilicon, a wholly-owned subsidiary of Huawei, was established.^[10]

Smartphone application processors

HiSilicon Hi6250

HiSilicon develops SoCs based on the ARM architecture. Though not exclusive, these SoCs see preliminary use in handheld and tablet devices of its parent company Huawei.

K3V2

The first well known product of HiSilicon is the K3V2 used in Huawei Ascend D Quad XL (U9510) smartphones^[11] and Huawei MediaPad 10 FHD7 tablets. This chipset is based on the ARM Cortex-A9 MPCore fabbed at 40 nm and uses a 16 core Vivante GC4000 GPU.^[12] The SoC supports LPDDR2-1066, but actual products are found with LPDDR-900 instead for lower power consumption.

Kirin 9000 5G/4G and Kirin 9000E, Kirin 9000L

Kirin 9000 is HiSilicon's first SoC based on 5 nm+ FinFET (EUV) TSMC technology (N5 node) and the first 5 nm SoC to be launched on the international market.^[32] This octa-core system on a chip is based on the 9th Gen of the HiSilicon Kirin series and is equipped with 15.3 billion transistors in a 1+3+4 core configuration: 4 Arm Cortex-A77 CPU (1x 3.13 GHz and 3x 2.54 GHz), 4 Arm Cortex-A55 (4x 2.05 GHz) and a 24-core Mali-G78 GPU (22-core in the Kirin 9000E version) The Kirin 9000L uses a 1+2+3 core configuration: 3 Arm Cortex-A77 (1x 3.13 GHz and 2x 2.54 GHz), 3 Arm Cortex-A55 (3x 2.05 GHz) and a 22-core Mali-G78 GPU with Kirin Gaming+ 3.0 implementation.^[32]

The integrated quad pipeline NPU (Dual Big Core + 1 Tiny Core configuration) is equipped with the Kirin ISP 6.0 to support advanced computational photography. The Huawei Da Vinci Architecture 2.0 for AI supports 2x Ascend Lite + 1x Ascend Tiny (only 1 Lite in 9000E/L). The system cache is 8 MB and the SoC works with the new LPDDR5/4X memories (made by Samsung in the Huawei Mate 40 series). Due to the integrated 3rd generation 5G proprietary modem "Balong 5000", Kirin 9000 supports 2G, 3G, 4G and 5G SA & NSA Sub-6 GHz connectivity.^[32] The SoC's TDP is 6W.

The 2021 4G version of the Kirin 9000 has the Balong modem limited via software to comply with the ban imposed on Huawei by the US government for non-chinese 5G technologies. The Kirin 9006C is a rebranded variant of the Kirin 9000E for the Huawei Qingyun L420 and L540 laptops.^[33][34]
