Literal meaningHaisi Semiconductor Limited Company

HiSilicon (Chinese: ; pinyin: H?is?) is a Chinese fabless semiconductor company based in Shenzhen, Guangdong and fully 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 U.S. instituted rules that require American firms providing certain equipment to HiSilicon to have licenses.[7]

Smartphone Application Processors

HiSilicon develops SoCs based on 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[8] 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.[9] The SoC supports LPDDR2-1066, but actual products are found with LPDDR-900 instead for lower power consumption.
