Loongson Technology, a leading Chinese chip company based in Beijing, unveiled on Thursday its fully self-developed CPU (central processing unit) architecture that uses an original instruction set, which has been hailed as a "historic breakthrough" by industry insiders.

The new infrastructure is named "LoongArch", short for "Loongson Architecture". It has passed the assessment of a leading third-party intellectual property evaluating agency, the company said.

An instruction set architecture (ISA) is the interface between computer hardware and software. It's the underlying architecture that supports the running of an operating system and a whole software ecosystem.

For example, the Windows operating system (OS) runs on U.S. company Intel Corporation's X86 architecture, and the Android mobile OS runs on ARM architecture developed by UK-based chip designer ARM Holdings.

The two best-known ISAs have been dominating on computers and smartphones worldwide since 2010, and both have very large industrial ecosystems including hardware like chips and software such as various applications.

Foreign CPU manufacturers have been using their ISAs as a tool to control the ecosystems and exclude competitors. Other companies have to pay royalties to get the licenses to develop CPUs compatible with them. If Chinese companies rely on those foreign ISAs, it's not possible for them to build an independent industrial ecosystem, according to the company.

"If we compare chip designing to writing articles, an ISA is like the language we use. Chinese people can write an article in English, but can never develop our national culture based on English," Hu Weiwu, chairman and chief scientist of Loongson, was quoted as saying by the Beijing Daily. He's also the chief engineer of the Institute of Computing Technology under the Chinese Academy of Sciences (CAS).

The "LoongArch", which is an outcome of the company's 20 years of hard work and experience in CPU development and ecosystem building, has nearly 2,000 proprietary instructions, the company said.

It's also compatible with other mainstream ISAs, allowing the efficient operation of complicated programs written for other architectures.

So far, Loongson's CPU chip based on the new architecture, named "3A5000", has been taped out and is under internal test. Its processing performance is very close to that of mainstream products on the market, Hu said. A complete OS based on the "LoongArch" has also run stably on computers using the chip.

"Only with our proprietary ISA can we build a new pattern in the information technology industry and form our own industrial chain," Hu told the Science and Technology Daily.

Loongson Technology was jointly funded and set up in 2010 by the Beijing municipal government and the CAS, with the goal of industrializing the technological achievements of the CAS in chip research and development.

YMTC is actually already facing an unofficial Embargo on Production Equipment by the US Govt.
So this has impacted production of its products.
The low yields of the 128 layer Nand is probably caused by using some new local equipment.
The local equipment takes time to mature.
However this yield problem should be solved by 2022 when they are planning to scale production massively of the 128 layer Nand.
2022 is also the time when they will tale delivery of the new SMEE DUVL and alot of other locally made equipment.
This is probably giving nightmares to the competitors of YMTC.
I haven't heard of the soft YMTC embargo (more likely that it's just a backlog) but fwiw, the equipment shipments to China are growing at a very rapid rate

Hi, do you mind giving a source for the data?

And can you say what do the numbers represent?
I am assuming it is the monthly value in ($) dollars. Is that correct?

I'm a trade lawyer in Houston; I don't deal with Chinese IC corporates but I do hear rumors (I won't say more due to atty-client privilege).

Yeah, it's in dollars from usatrade.census.gov. You need to create an account though to get US trade data

Thanks for posting. Do you know if that is just equipment purchased FROM the US? Fact is that is great news and really makes sense, even if it is just for the US!

Ah ok, i see. Btw thanks for posting this kind of data to the forum.

AFAIR this is the first time I see data on this thread from that source so it is very helpful for understanding the Chinese IC development based on importing IC equipment

Via Vincent seem like the SMEE lithograph machine is being installed in this factory

Qingdao New Core semiconductor packaging production facility started construction on April 2020 and completed on December 2020. 46 pieces of equipment have moved into the facility already and on July 20 SMEE’s lithography machine for semiconductor packaging got delivered to the facility.

Test production starts in October and full production starts in December. The production line is focus on 5G and AI chips.

According to the micro-network news, on July 20th, the opening ceremony of the first lithography process equipment of the Qingdao new core high-end packaging and testing project was held in the West Coast New District of Qingdao, Shandong, marking that the project has entered a key node and laid a solid foundation for the end of the year. basis.

It is reported that the equipment entering the field this time is a SMEE package lithography machine.

According to the news of international investment promotion in Qingdao West Coast New Area, 46 machines and equipment have been moved into the plant area of the project. It is expected that trial production will be carried out in October and mass production capacity will be formed in December. After the project is put into production
, it will greatly promote the transformation and upgrading of the integrated circuit industry in the new district and even Qingdao, help improve the industrial chain, and promote high-quality economic and social development.

In April 2020, Qingdao's new core high-end packaging and testing project will land in the new area through online "cloud signing", and will mainly use the world's leading packaging technology to package the current rapidly growing demand for 5G communications, artificial intelligence and other application chips. The project was signed in that year, landed in that year, and capped in that year.

On April 15, 2020, the Qingdao Semiconductor High-end Packaging and Testing Project passed an online "cloud signing", and the project landed in the China-Japan (Qingdao) Local Development Cooperation Demonstration Zone. The China-Japan (Qingdao) Local Development Cooperation Demonstration Zone is located in the West Coast New District of Qingdao. According to news at the time of the contract, the project has a total investment of 1 billion yuan, mainly using the world's leading high-end packaging technology to encapsulate application chips such as 5G and artificial intelligence that are currently in rapid growth in demand. On December 22 last year, the main plant of Qingdao Semiconductor's high-end packaging and testing project was successfully topped off.

From this point of view, Qingdao's new core high-end packaging and testing project may be Qingdao Semiconductor's high-end packaging and testing project. (Proofreading/Xiaobei)
Great news! This litography machine is for packaging. Does anyone know if it is already a 28nm, or older tech?
