China chip domineering official announcement, pure domestic high-performance chips arrived as scheduled! For the current stage of scientific research and development, what kind of chips can be obtained, directly determines a country's scientific and technological ceiling, since the implementation of chip rules, it has become difficult for Chinese companies to obtain high-end chips, and some companies have been completely interrupted supply.

In terms of packaging: Changjian Technology completed the mass production of 4nm chip packaging technology

News on December 24, 2022, Changjian Technology recently said on the interactive platform that the company has achieved the packaging of mobile phone chips in the 4nm process. In the domestic integrated circuit packaging industry, Changjian Technology is an industry giant.

It adopts a multi-dimensional advanced packaging technology called XDFOOI, which can realize the packaging of 4nm mobile phone chips.

Loongson Zhongke rose strongly

Although Huawei can design 5nm chips, but in the core instruction set architecture, EDA design software, still rely on Western companies, such examples abound in China.

In order to ensure the technical advantages of Loongson, the Chinese Academy of Sciences has invested a lot of funds in R&D and production and provided the most advanced software and hardware support. Loongson Zhongke has always insisted on independent development in terms of research and development.

Their principle is: "Do not accept overseas capital and resolutely realize the autonomy of core technology!" "The development process of Loongson Zhongke can be summarized in one sentence: from scratch to gradually grow and expand. One step at a time.

Timeline of Loongson's development

In 2008, the Chinese Academy of Sciences and the Beijing Municipal Government jointly led the establishment of Loongson Zhongke Technology Co., Ltd., aiming to industrialize the R&D results of the "Loongson" processor by relying on the research and development technology of "Loongson" for more than ten years.

On May 13, 2020, as the first batch of initiators, the "Digital Transformation Partnership Action" initiative was launched with the National Development and Reform Commission.

On June 24, 2022, Loongson Zhongke Technology Co., Ltd. made its initial public offering and was listed on the Science and Technology Innovation Board.

To ensure the "pure domestic" of the chip, the first thing to solve is the problem of instruction set architecture, Loongson Zhongke early adopted the MIPS architecture, originally thought that the purchase of permanent patent authorization, can be foolproof, but after the MIPS parent company was acquired, there were also corresponding problems in patent authorization, Loongson Zhongke had to start to build an independent instruction set architecture.

After years of efforts, the fully autonomous "loongArch" architecture was born, and passed the evaluation of professional institutions, successfully getting rid of the situation of dependence on the underlying core technology, and Loongson Zhongke also began to move towards the road of "pure domestic".

Domineering

The 3A6000 was born

Loongson Zhongke has delivered a number of chips, but most of them are low-end chips, the scope of use is also limited, the follow-up goal is also placed on the breakthrough of high-performance chips, as early as November 2022 performance briefing, Loongson Zhongke revealed: "High-performance PC processor 3A6000 will be completed in the first half of 2023!" ”

On January 11, there was exciting news that Loongson Zhongke 3A6000 completed tape-out, which is a general-purpose CPU using 14nm process technology.

Compared with the previous generation of chips, the simulation running score is increased by 30%, the floating point performance is increased by 60%, and the chip area is reduced by 20%.

3A6000 chip is Loongson Zhongke based on LoongArch architecture design, due to the autonomy of the architecture and the support of the manufacturing side, this is almost 100% domestic chip products.

With high-performance characteristics, it is of key significance in independent innovation and ecological construction.

"National team" Loongson Zhongke domineering, domestic 14nm high-performance chip 3A6000 tape-out to 100%, from Loongson No. 1 to Loongson No. 2, and then to today's 3A6000, every small technological progress, is a big step in the development of mainland chips, in the future, "Loongson" as China's independent research and development, internationally competitive high-end processor brand, has a strong core technology and product advantages, will let the world witness China's chip power!
