OpenKylin is the OS, one still needs to re-compile all the apps to run on the Loongson CPU which majority of the developers aren't willing to do with such a tiny niche market.

This is why China should push RISC-V because any app that runs on RISC-V instruction set can run on Chinese made RISC-V CPUs

Re-compiling apps doesn't take a lot of time. When you run ubuntu, you can use apt-get command and select from a long list of apps to install. If Loongson had a good product and gets used by important ministries, Chinese gov't can just encourage any software supplier to also generate binaries for LoongArch whenever they are putting in new releases.

RISC-V is still not developed enough to take over HPC or desktop market yet. Until then, Hygon has full control over x86 license and instruction set. Same with Phytium with ARMS.

Example of application of solid state microwave source on diamond semiconductor films.

There is no internal electrode in the cavity of microwave plasma chemical vapor deposition (MPCVD), which can avoid the pollution caused by electrode discharge. Its operating pressure range is relatively wide, and the generated plasma has high density, large area, high stability, and no It is in contact with the vacuum wall, thus avoiding the contamination of the film by the wall. Therefore, microwave plasma chemical vapor deposition (MPCVD) has become one of the most promising high-quality diamond film deposition methods due to its unique advantages.

In the past, people habitually used the well-known magnetron power source to apply to the MPCVD system. With the rapid development of technology, it has become a new trend to replace the magnetron solution with the solid-state RF microwave power source in the MPCVD system. trend.

Schematic diagram of the application framework of solid-state microwave sources in MPCVD systems (taking 6kW as an example)

Application advantage analysis of solid-state microwave source in MPCVD system

In the MPCVD device, various factors such as microwave frequency, cavity size, and sample base will lead to the electric field distribution and plasma state and distribution in the cavity. The following is the data analysis of a bachelor from Taiyuan University of Technology:

Picture 1


(Figure 1)
In the MPCVD device, even a frequency change of 10MHz will cause strong changes in the electric field and plasma intensity and distribution state in the cavity



picture 2


Figure II)
In the MPCVD device, the size of the resonant cavity causes strong changes in the electric field and plasma intensity and distribution state in the cavity

picture 3


(Picture 3)
In the MPCVD device, the position of the sample base causes strong changes in the electric field and plasma intensity and distribution state in the cavity

The Wattsine solid-state power source has controllable frequency and phase. We can adjust the frequency and phase of the microwave source to compensate for the distribution and change of the electric field distribution and plasma state caused by various changes in the cavity size and sample base. .

The MPCVD device using Wattsine's solid-state power source will not change the working state of the device due to the replacement of the power source, and will not need to re-adjust and set the working parameters of the device.

Are you naive , do you know about consequences if china bans apple ?
USA is going to sanction entire Chinese mobile phone & laptop and other digital companies . All those companies like xiaomi, oppo, lenovo, would collapse not just in china but outside of china too, because all of them rely on android os, nobody would buy Chinese phones which doesn't come with Android OS & other countries would gain all those jobs which china is going to lose because of massive collapse of digital goods .

Just look at example of huawei, how many people outside of china is buying huawei phone now ?

Do you even know what you are talking about? Chinese mobile phone companies don't rely upon Android OS within China. Outside of China, if all Chinese companies move to new system, Android OS would be toasted.

Did Huawei collapse after the US sanctions? So you are basically just making an emotional comment due to your worship of the West.

China should retaliate by banning Apple and Boeing and GM and Ford from the Chinese market. If the Americans want to play dirty with sanctions, then Chinese should fire back. Let's see who has more to lose.

Pragmatism should be the order of the day, not emotion. Such emotionally charged decisions cannot end well, and temporary carthasis is always lesser then material gain. The sanctions are arguably hurting American companies more and have motivated Chinese companies to accelerate domestic efforts. Letting the USA repeatedly shoot its foot is in China's best interest; there is no need to retaliate.

Looks like Kylin is now installed on all the China Railway company data centers. UOS is installed in the southern electric power. But in consumer market, Microsoft still has 87.5% of market share and MacOS with another 10.1%. As such, Chinese OS is very much for SOEs and gov't organizations at this point. Even replacing all of these corporate desktop CPUs and large data centers would probably take up all the CPU production from the domestic players.

There will always be room for Chinese OS.
There are still so many poor rural areas to be developed.
Furthermore, MacOS share in China 20 years ago was basically absolute zero, and Microsoft licensing revenue was not significant.

More generally, speaking as a neophyte
To me, the more immediate goal of RISC-V is to seize the marketshare in micro-controllers from ARM Cortex-M series. Already we see Western Digital moving in this direction. Chinese companies can develop these RISC-V chips for special applications like battery chargers, automotive, etc. and worry about desktop/end-user later. From what I've read, RISC-V is attractive in these applications because they are low margin products and saving the licensing is extra value, and open architecture means it is possible to add custom logic blocks without following the segmentation that other companies implement.

TSMC factory in Arizona is going to be larger than ever before - all the world's technologies will belong to the United States in due time, no matter where they may have geographically originated. Not only will there be a steadily advancing foundry providing TSMC's best technologies and engineers for the United States (for free); it is going to even larger than before with $40 billion in capital expenditures.

Lets suppose that this is probably not going to be TSMC biggest mistake, let suppose that the differences in wages and working culture is not going to eat this venture revenue "IDK, for some reason the pure and play foundry model works in Asia". Who are going to be this foundries clients? The clients are not going to be mainland China companies, nor Koreans. The main clients are probably going to be big US companies, so the DPP has trapped Taiwan, unable to sell the best chips to mainland China companies and losing revenue to the U.S.
If this venture is "successful" it could probably give meaning to the famous phrase "To be an enemy of the US is dangerous, but to be a friend is fatal" because this could doom that island precious semiconductor industry.​

What he is saying is that US has China by the balls via consumer CPU chips and Android OS, hence the entire reason for this thread. Stoping the flow of current x86/arm into Chinese manufactures pretty much cripples those companies since a huge portion of those companies rely on products with x86/arm for revenue. Huawei is a diffrent beast as telcom gear and services for carriers was always their core competency and consumer goods were a side project that just happen to exploded.

Western customers rely on apps that rely on GMS like google maps not to mention all the validated western apps in the play store, hence sales of huawei phones pretty much cease in europe after the android ban. Not many sane people would want to login to their bank or netflix via an app downloaded at apkpure, even if it did not rely on GMS. The "New Red Scare" will prevent Chinese OS penetration in the "west" but I think it will have good opportunity in the rest of the world.
