First of all, we should distinguish between "thinking about the sea" and "thinking about the small sea". Huawei brand Huawei Hisilicon is divided into "big sea thinking" and "small sea thinking". "Hisilicon" refers to Huawei's "Hisilicon and Devices Business Department", which is also commonly referred to as "Hisilicon". As early as 2004, Huawei registered Haisisi as Shenzhen Haisisi Co., Ltd. in Shenzhen.
"Little Hayes" refers to Huawei's "terminal chip business department", which is often called "terminal chip". It actually belongs to CBG (that is, consumer BG), not under Hayes.
For a long time in history, "Little Hayes" and "Shanghai Hayes" are actually two unrelated concepts. However, on 20 18, Huawei registered Little Hayes as Shanghai Hayes Technology Co., Ltd. in Shanghai, directly linking Little Hayes with Shanghai Hayes.
It is worth mentioning that when Huawei established "Shanghai Hisilicon", it also included Hisilicon, a "bigger network celebrity" department under Hisilicon Connection Chip Development Department, in the terminal chip business department for a short distance, so in fact, the current Hisilicon is bigger than the previous Hisilicon. Although "Shanghai Hayes" is registered in Shanghai, its headquarters is actually in Shenzhen (including Dongguan).
The chips of "Dahaisi" are generally used by Huawei and are not taken out. The main products are Kirin series, Ba Long series, Tiangang series, Kunpeng series and Shengteng series. "Dahaisi" generally adopts international advanced chip technology, mostly based on the technology of 14nm and below. For example, the Kirin 9000 chip of Huawei's previous generation was equipped with the most advanced TSMC 5nm process at that time.
"Xiaoheisi" is mainly engaged in external supply services, and its chips are mainly sold to other manufacturers. The main products are Lingxiao series, low-end Ba Long series and Budika series. Chip categories are mainly set-top box chips and security monitoring chips. The chip manufacturing process used by "Little Black Silicon" is somewhat backward, mostly based on 28nm and above processes.
In 2022, Huawei made a large-scale adjustment to the organizational structure of the enterprise. Before the structural adjustment, "Haisisi" was called "Haisisi Devices Division", which was affiliated to 20 12 Laboratory. "Little Hayes" is called "Terminal Chip Business Department" and belongs to CBG (that is, consumer BG).
Because the company is registered as "Shenzhen Haisi Co., Ltd.", it is sometimes called "Shenzhen Haisi"; Because the company of Little Hayes is registered as Shanghai Hayes Technology Co., Ltd., it is sometimes called Shanghai Hayes.
However, CBG was split in this reorganization: the main part of CBG was renamed as Terminal BG, and the "Terminal Chip Division" under CBG was also upgraded from the second-level department to the first-level department with the new name "Shanghai Hayes".
At the same time, when Huawei established "Shanghai Hisilicon", it also included Hisilicon, a "bigger network celebrity" department under the development department of Hisilicon Connection Chip, into the terminal chip business department in a short distance, so in fact, Hisilicon is bigger now than before.
That is to say, we can roughly understand it as follows: Little Hayes = Shanghai Hayes = original terminal chip division+Hayes short distance, while Big Hayes = Shenzhen Hayes = Hess and Devices Division. However, since both Haisi and Xiaoheisi have sites in many cities, using the word "city+Hayes" will bring a lot of conceptual misleading.
Then, about the concept of "Hayes". Because Xiaoheisi used to be called the terminal chip division, everyone used to call Dahaisi Hayes and Xiaoheisi the terminal chip.
The actual registration time of Shanghai Hayes Technology Co., Ltd. is 20 18, so "Shanghai Hayes" and "Hayes Shanghai" are actually the same thing for a long time. But later, because the concept of Shanghai Hayes Technology Co., Ltd. appeared, the conceptual confusion gradually appeared.
At present, it is generally believed that Shanghai Hayes = Xiaoheisi and Hayes Shanghai = Dahaisi Shanghai Branch, so they are really different now.
In fact, this year's independence is actually little Hayes, that is, little Hayes has become a first-class department, and big Hayes (that is, the real Hayes) still belongs to the 20 12 laboratory. Therefore, the answer to this question is no, Hess is not independent. Shanghai = small = former terminal chip business department+Hayes short distance.
