The two "stars" of the Asia Star program did not yet know that the polar bears were preparing fragrant bait for them, but ESA had already willingly eaten the bait of the Aviation Development Commission.

The chief engineers of Beijing, the space agency and Xinyuan got the basic design drawings and launch routes of the ESA HVE rocket, and discussed them together in front of them.

The engineers sent by ESA (mainly Italian and hairy) humbly listened to the opinion of the East.

In terms of space technology, Europe can be said to have its own unique and excellent technology, and there is really nothing to brag about in rockets.

In the past, Ariana 5 could still blow it, but it was pressed to the ground and rubbed by the Long March 10, even if the latter had some problems with the first shot, it was not fatal, it was still a powerful giant rocket, not to mention Xinyuan.

Anderov looked at the basic drawings of the HVE rocket, carefully evaluated the technical data of ESA's 5.2-meter-diameter rocket body and EAP booster, and nodded slowly in the expectant eyes of ESA experts.

"There is no problem with the basic design of the HVE, and the material of the arrow body is also very good."

But before ESA could rejoice, Anderov made another twist:

"But four solid thrusters are too expensive, and the tremor is relatively large, so it is better to change to two, connect more superchargers in series for the EAP, and increase the thrust of a single unit to 1200 to 1400 tons, which is the level of the Space Shuttle SRB, is there any technical difficulty?"

Hearing this, ESA experts looked to Simon, an expert from the CNES (Space Agency), who was deeply involved in the development of the Ariane 5 rocket and was also the chief engineer of HVE.

For EAP Simon's natural understanding, the answer was quickly given:

"There is no problem, maybe the combustion chamber will be strengthened, but there will be enough time to complete the manufacture of the new EAP in 2017."

Anderov: "Then I don't have much more to say, did you really decide to develop the second and third stage engines of the HVE yourself?" ”

Simon: "The second and third stages only need to be slightly modified to Vulcan 2, and we think it's reliable. ”

On the side of the Space Agency, Yun Hongjun, the chief engineer of the Long March 10, also gave his opinion:

"Different from SLS, although HVE is also a solid-liquid mixed propulsion, but the core stage of HVE is a kerosene engine, and the thrust is very strong, if you want to take into account the core stage VV-1 (Veneto 1) to launch and form HVE alone, the combustion time of the first stage needs to be considered in a compromise to control the dead weight within the appropriate range."

The take-off mass of the HVE is expected to be about 2,300 to 2,500 tons, which is a real giant rocket.

Anderov: "Now that the VV-1 project has been established, 2 K400 and 16 YF100V engines can be ready for shipment, and these engines will be shipped in December, what do you think?" ”

Sagar: "No, by air, we can't wait for them to be in place, and your engineers can get there soon?" Your ADC is the fastest part of the entire Selene project, and we plan to complete the VV's first-stage rocket body design in 6 months, so please customize a reliable recovery system. ”

Anderov: "If the maintenance is in accordance with the process, we guarantee 20 trouble-free recycling, and if there is a problem, we will compensate accordingly." ”

Simon: "Thank you, please sign the contract as soon as possible, I can't wait to send HVE into space." ”

Anderov: "Wait, are you interested in buying Space Shuttle insulation tiles, the kind that can be reused five times?" ”

ESA expert: "......"

Simon looked at the representative of ESA who was in the same room, and the latter gritted his teeth and said:

"Customized...... Is there a charge? ”

……

Huawei Labs.

Yu Chendong picked up a black integrated SOC, the silk screen on it is SMIC, which is a chip manufactured and packaged by Huaxin International, and the corner mark is 65H4, which means the fourth iteration of the 28nm process after multiple exposures of the 65nm lithography machine.

This is the first Kirin SOC to use Xinyuan EDA software, HiSilicon Kirin 959 processor.

After solving 97 key problems, under the leadership of the Commission of Science and Technology, the national semiconductor industry began to charge towards the ternary.

97 problems solve the problem of using infiltrated multi-exposure 65 and 45nm lithography machines to produce 28nm chips with acceptable yields, and at the same time support the establishment of a good 28nm chip production line, the cost is only about 5% to 7% higher than TSMC.

A more professional new generation of 28nm lithography machine is being developed intensively, and it is expected to complete the R&D and manufacturing of a new generation of lithography machine in early 2018.

At the same time, Ziguang, ZTE, Wuhan Digital Science and Technology Research Institute, Huake Loongson and other enterprises carried out the research and development of related processors, and after discussion, Huawei has achieved equity reform and became the first batch of private enterprises to develop ternary mobile phone processors.

After learning that China had such a strong ternary technology reserve, Huawei immediately invested heavily in it and began to digest the ternary circuit design ideas and underlying architecture design provided by Xinyuan.

After discussion, a group of executives believed that the country would inevitably strive to promote ternary chips and the ecosystem in the future, so they asked HiSilicon Labs to make ternary chips as soon as possible, and began to compile the X language system from the bottom up.

The operating system is actually quite simple, and in the summit, Huanghe Semiconductor said that Xinyuan's XOS will be open to the outside world, rather than being closed like IOS, and hopes to achieve the unification of the mobile and desktop systems by starting from scratch.

That is to say, the future popular mobile phone-computer system is consistent and seamless switching, taking advantage of the current blank paper to paint, Yellow River Semiconductor will take this as a condition to require manufacturers to unify from now on, and the passage is relatively smooth.

Huawei found that although XOS is indeed very simple and has no software, the underlying architecture is not at all like the unexpected improvement of the new system, and it can be used almost like Google's android with an optimized interface, mainly to develop a software ecosystem.

In order to reduce the design time, HiSilicon Kirin moved the design of the Kirin 950 octa-core processor to reduce the design time, and then optimized and improved it according to the characteristics of the ternary circuit.

The Kirin 950 has about 3 billion transistors inside, and after the transformation to the ternary Kirin 959, the number of equivalent MOSFETs has dropped to about 2 billion, but the comprehensive performance has increased by 15%, which is almost a generation difference, surpassing the Qualcomm Snapdragon 820, the most powerful processor in the consumer market.

The Kirin 959 is naturally equipped with a new ternary RAM and ROM, although the use of diode analog FETs will increase the space of a single basic component of the ternary chip, resulting in a smaller number of basic elements, but the ternary represents more states, and it is much more efficient with the same ternary chip.

In the ternary system, 9 ternary bits are used as one byte, which is different from the 8 bits per byte in binary.

So a ternary word energy-efficient storage of 19,683 states, instead of 256 binary bytes, is about 76 times longer than binary bytes!

This is enough to store the most commonly used Chinese characters and quite a few rare characters, after all, there are only 3,000 Chinese characters commonly used.

And there are also differences in units:

Westerners prefer to use 1000 to divide, while binary computers stipulate 1KB=2^10 (i.e. 1024)B, and manufacturers use 1KB=1000B, so many times the storage manufacturers claim that 1GB is only 931MB in the eyes of binary computers, which is why the free space of the 1000G hard disk you buy is only 931GB.

In ternary computers, Xinyuan stipulates 1KB=1000B, 1MB=1000KB, and 1GB=1000MB.

If we simply convert according to the storage state, 1B (ternary) = 76.8867B (binary)

Of course, in fact, no, according to the regulations, the space of 1 byte of ternary and 1 byte of binary can only be put down 1 number or English letter (Chinese characters), most of which should be used more or less, but it can still greatly reduce the size of the file.

Especially for the Chinese Internet is still very advantageous, after all, 2 8-bit bytes in binary can store the next Chinese character, and 1 9-bit byte in ternary is enough.

Huawei's next-generation flagship machine decided to be named mate10 directly, equipped with Kirin 959 processor and 9+162G running memory and storage space, and ZTE and Unisplendour chips also followed, Yu Chen Dong wanted to compete for this first.
