Literal meaning Haisi Semiconductor Limited Company

HiSilicon (Chinese: 海思; pinyin: Hǎisī) is a Chinese fabless semiconductor company based in Shenzhen, China and fully owned by Huawei.

HiSilicon purchased licenses from ARM Holdings for at least ARM Cortex-A9 MPCore, ARM Cortex-M3, ARM Cortex-A7 MPCore, ARM Cortex-A15 MPCore,[1][2] ARM Cortex-A53, and ARM Cortex-A57 and also for the Mali-T628 MP4.[3][4]

HiSilicon 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.[5]

K3V2[edit]

The first well known product of HiSilicon is the K3V2 used in Huawei Ascend D Quad XL (U9510) smartphones[6] and Huawei MediaPad 10 FHD7 tablets.[7] This chipset is based on the ARM Cortex-A9 MPCore fabbed at 40 nm and uses a 16 core Vivante GC4000 GPU.[8] The SoC support LPDDR2-1066, but actual products are found with LPDDR-900 instead for lower power consumption.
