I ask you to build tractors, but you build rockets?

NACA had little reaction to Arbor's outstanding performance in aerospace this year and his use of the space station to win over neighbors and exchange interests.

In other words, I don’t know how to react.

Because this year is quite special, Ao Xiaohei has already imagined in media interviews how he will play after retirement and will not care about anything at all.

During Xiaohei's 8 years, he started to cut off George W. Bush's "Constellation" large-scale space program. He tortured NACA so much that he was forced to cut off a lot of flesh.

As a result, since the launch of the Artemis program last year, even if Xiaohei didn't want to, he had to continue to invest in the space field. NACA felt that Xiaohei looked quite pleasing to the eye.

I don’t expect the next boss to get more batches, as long as I can maintain the current level.

It's not yet July, and the old witch seems to have a good chance of winning. NACA feels that it's quite satisfactory and it shouldn't have much impact on the Artemis plan.

As for the blond old man, that faction probably didn't plan to run for election, so they just randomly promoted a real estate developer and part-time elderly idol. It's not worthy of any additional attention at all.

…

A strange piece of news has recently appeared in the domestic semiconductor industry: ternary chips have been put into practical use, and they are better than binary chips.

Outsiders don’t know what they are talking about, and insiders don’t understand either, but they sneer at it.

Only a handful of people at the cutting edge really noticed something was wrong.

Things start in April.

At the end of April, Xin'an's two new cars, a large SUV with a price of 300,000 yuan for families and a family car with a price of 150,000 yuan, accepted reservations.

Both models are equipped with a new generation (castrated version) of the XW161 intelligent driving system, which has slightly better battery life and performance than its peers.

However, the most eye-catching announcement is that after the cumulative sales of 300,000 units of the two models, 20 lucky car owners will be randomly selected and sent spaceship tickets.

This situation of relying on aerospace companies to do whatever they want is despised by major car manufacturers because they have no ability to fight back.

Only Volkswagen announced that it will also conduct sales statistics for the three models released this year, and will select 4 places when the cumulative sales volume is 300,000 vehicles.

Where do these 4 places come from? Of course I bought a seat from Xinyuan Aerospace.

Although it’s a bit scarce, and it’s a reserved seat on a firm ticket, so you have to choose to share the flight with others, but mosquito meat is also money, and it’s a good start.

If every car company wants to compete, Xinyuan will make money in the end.

It's a win-win situation.

But this is not the point. The point is what Baidu discovered.

Last year, Baidu began to follow Google's idea of ​​​​intelligent driving, and the XW151 turned out to be so powerful. I quickly bought one and took it apart to see why this highly intelligent driving system that has entered practical use is so powerful.

As a result, their engineers were beaten to death in front of the ternary wall and failed to crack the secret of XW151. They could only change directions and analyze it in a clumsy way from the hardware aspect.

When you take apart the motherboard, the first thing you see is the most familiar hard drive.

Micron enterprise-grade solid state, good stuff, dismantled.

After searching around the motherboard, Baidu engineers discovered a surprising problem:

I have never seen the interface protocols on this motherboard before, they are all unfamiliar wiring harnesses!

But looking at the densely packed logos on the motherboard, it’s definitely not something a small factory just makes do with, but it has its own system.

They found a way to make an adapter and continued to crack it. After more than half a month of self-doubt, they finally confirmed that from the chip to the external components on this motherboard, at least they were not available on the market and should be custom-made. products.

What’s even more frightening is that the XW151 system is ternary!

This conclusion was so amazing that they couldn't believe it, and they verified it many times before confirming it.

Ternary, how do you copy this thing? They don’t even know what language the ternary code is written in!

In the end, Baidu cooperated with the Microelectronics Laboratory of Jiaotong University in Shanghai to remove the X32115 chip, polish it and analyze it.

That is to say, use a laser to erase the chip package layer by layer to expose the innermost circuit part, and then use an electron microscope to observe the transistor structure.

During this process, they first determined based on the packaging process that these chips were manufactured by Huaxin International. The core part used the 28nm process, and the periphery was doped with 45nm and 55nm processes. Then they discovered the unique field effect transistor structure.

That is, the principle of two transistors simulating a ternary basic element is very simple, but the laboratory was still extremely surprised by this conclusion.

There are more than 800 million field effect transistors, which means that behind this ternary chip is a mature EDA design, which is the result of more than ten years of hard work by countless semiconductor people!

But where on earth has there been an organization that has conducted long-term follow-up research on ternary components and systems?

If the chip's packaging hadn't indicated that it was manufactured by Huaxin International's 28nm OEM, they would have suspected it was an alien product.

Then they asked Huaxin International for verification, and Huaxin International briefly disclosed a little information about these ternary chips, and then remained silent.

The X32115 chip has been iterated again. This year, the X32116 is produced. The manufacturing process remains unchanged, but a lot of optimizations have been carried out. Special performance has been enhanced while power consumption has not increased.

And the cost has also come down. The average price of X32115 is almost 3,000 yuan, and the average price of X32116 is only 2,500 yuan, which is much cheaper.

Coupled with other supporting chips and storage devices, Huaxin International made a lot of money. According to the wishes of the funder, it did not make any publicity, so by the time it was taken seriously, it was already too late.

Therefore, the Science and Industry Committee has now learned from the shocked Baidu and Shanghai Jiaotong University, as well as the reluctant Huaxin International, that Xinyuan has a mature ternary system of software and hardware research and development, and may have surpassed the current mainstream level. .

The current mainstream chip manufacturing processes in the world are still 14nm and 16nm, and 28nm has fallen behind.

As a result, the performance of the ternary chip using the 28nm process actually exceeded that of the binary chip using the advanced process?

The Science and Technology Commission first dismantled more than a dozen X32115 and X32116 for analysis, and then conducted a detailed evaluation of XW151.

The person who received the analysis task was Fu Weiwu, the leader of the Loongson team.

According to external analysis, the current 3B2000 released by Loongson can compete with the Core i3 550 released in 2010. It can be regarded as... at least it has a good prospect.

Fu Weiwu was very surprised when he got the X32116. It knew about Xinyuan's intelligent driving technology, but it was related to the GPU. He thought Xinyuan had bought a professional card from NVIDIA or AMD.

Then someone told him that the X32116 in his hand was actually a mature domestic ternary processor, and its performance crushed mainstream deep learning cards? Is there a supporting ternary system?

With a skeptical attitude towards life, Loongson and several experts from the Chinese Academy of Sciences gathered together and conducted intensive analysis on X32116 and XW151 for more than a month.

Finally, when the Science and Technology Commission came to ask if they were sure, Fu Weiwu nodded;

When asked if his performance was strong, Fu Weiwu nodded;

When asked whether the ternary design was complete, Fu Weiwu nodded;

Finally, he asked Fu Weiwu why he didn't speak, and the latter finally spoke:

"This chip has challenged my life values. In my understanding, neither X32116 nor XW151 should be something that can appear on the earth, at least not silently."
