Chapter 755 ARM (Second Update)

The difficulty of this flying scooter using a turbofan engine lies in the miniaturization of the turbofan engine.

The Tomahawk cruise missile of the Bald Eagle will be officially put into service next year.

In fact, the appearance of cruise missiles is similar, and the one designed by Liu Hai is also similar, but now the accuracy is a problem.

In 2020, cruise missiles were guided by multiple methods, including cruise phase inertial + terrain matching + satellite-assisted navigation, and terminal guidance was optical scene matching guidance.

It is impossible now, so the accuracy is a bit worrying.

Of course, for large fixed bases, this flying scooter is faster and more powerful than the original flying scooter.

For the same 1,500 kilometers, the previous flying scooter flew at a speed of more than 200 kilometers per hour, and it took seven hours to fly, while this flying scooter with a turbofan engine can cruise at a speed close to Mach 0.9.

That is, it can reach 1,125 kilometers in one hour.

In fact, in Liu Hai's view, this cruise missile does not have an advantage over the flying scooter.

Because the cost of the two is completely different, this kind of flying motorcycle with a turbofan engine cannot be manufactured by any factory, while the original internal combustion engine version of the flying motorcycle can be manufactured by any machinery factory.

Whether it is from the perspective of war potential or cost-effectiveness, the flying motorcycle has unparalleled advantages.

10,000 flying motorcycles are easy, but 10,000 cruise missiles are too difficult.

In addition, breaking through other people's air defense network still depends on saturation strikes, and relying solely on performance is still unreliable.

Even if the opponent can be warned and know that 10,000 flying motorcycles are coming.

To intercept these 10,000 flying motorcycles, how many fighters, helicopters, and air defense missiles are needed.

How much does a simple air-to-air missile cost, and how much does a flying motorcycle cost?

What's more, it costs money for a fighter to take off.

Of course, it can be used in combination at this stage, that is, use the flying motorcycle to open the way, then calculate the time, and then launch the turbofan engine version of the flying motorcycle.

Then try to reach the destination at the same time, so that the attack effect is the best, because the destructive power of the turbofan engine version of the flying scooter is much greater than that of the fuel version.

Of course, this will be difficult later, because the radar will increasingly believe that it can lock the most threatening target by calculating the speed of the target.

But no matter what, 10,000 flying scooters exceed the upper limit of all radars that can track and calculate.

As soon as the radar is turned on and captures 10,000 flying scooters, it may be paralyzed directly.

In 2020, Liu Hai found that the war has returned to the army era.

Although the fat goose destroyed all his brother's airports in the first wave, why didn't the fat goose gain air superiority later, and even the number of aircraft dispatches was pitiful.

The main reason is that there are too many air defense weapons, the larger ones have special s series air defense missiles, the smaller ones have air defense tanks, and the smaller ones have various individual air defense weapons.

To be honest, air superiority is not so important in 2020.

This is probably what no one expected.

Of course, the deputy director in charge of military industry also knows the advantages and disadvantages, but any weapon has disadvantages.

We should have what others have, and we should also find ways to do what others don't have.

Of course, the deputy director in charge of military industry pays the most attention to the No. 001 teaching building. The main building of this building was completed very quickly, but the internal facilities were slower.

The main thing is that Comrade Liu Hai must make these internal facilities well, and some of the facilities can operate successfully.

In the end, the test data was taken away by the deputy director in charge of military industry. This is the top secret test data.

Although it is okay to give it to Comrade Liu Hai, it is useless for Comrade Liu Hai to ask for it. It is dangerous to keep it in his hands.

Liu Hai looked at the time and drove to Fenghuo Technology Company.

"Boss." Ni Nan has been waiting in the company for half an hour.

Until now, Ni Nan still doesn't know who his boss is. Anyway, he hasn't seen the boss in any public information.

Now Ni Nan is convinced that he is the boss, because the boss has a lot of money, is willing to delegate power, and is willing to do technical research, unlike some people who just want to buy foreign technology and sell it back to their own people to make money.

"How is the test going?" In 1981, IBM launched the PC DOS computer, which sold 25,000 units in 1981. This year, it will sell 190,000 units, and next year it will sell 700,000 units.

When it was launched last year, Liu Hai asked the company to buy one and disassemble it, and then imitate it.

Liu Hai replaced the 8088 chip used by IBM with the 8086 chip to grab the PC computer market.

And before the establishment of Fenghuo Technology Company, it purchased the production license for the mouse.

The mouse was truly launched on the market in January 1983 when Apple launched a new generation of computers with the mouse.

Of course, the computer launched by Apple in January next year suffered a major failure, mainly because it was too expensive. A computer cost more than 9,990 US dollars, which is close to 10,000 US dollars.

More companies are willing to use cheaper IBM PC-DOS computers.

Apple computers were produced and eventually ended up in a landfill in 1986.

"The test has been completed, and it is better than similar products because the chip we use is better than the other party." Ni Nan took out the information and said.

Liu Hai did not choose the design of the screen and chassis integrated into the current computer, but separated the screen from the chassis.

Most computers now have screens and chassis together, and Liu Hai also has a modular design, that is, the power supply, heat dissipation, fan chips, etc. can be disassembled.

In the early days, Apple still thought that the cooling fan was a hindrance, so the cooling fan was removed during research and development, but later it was found that it would not work without this thing.

In his previous life, Liu Hai liked to tinker with computers by himself. Of course, at that time, he could do whatever he wanted with the computer accessories and buy parts and match them at will.

So Liu Hai asked the company to design this computer according to his own ideas.

Ni Nan also agreed with his boss's advanced ideas.

"How is the chip?" Liu Hai looked at the test report and was still concerned about the chip.

Because Intel 386 chip is an epoch-making chip, they have launched 286 chip this year.

"It's a bit difficult for us to catch up with Intel with X86 architecture chips."

"The reduced instruction set chip is already being tested, thanks to the boss who bought a lot of professional journals and materials." Ni Nan said.

Liu Hai nodded. RISC (reduced instruction set computer) has been popular in Silicon Valley in recent years, so he came up with the idea of ​​ARM architecture.

The first 32-bit ARMV1 in history has only 45 RISC reduced instructions and five different addressing modes. Of course, their team will not start working on this chip until October next year.

In fact, the ARM team initially targeted the 80286 chip, but Intel didn't care about others at all.

They will not work on this chip until October next year when they are desperate.

In fact, our country is not short of semiconductor talents now, especially for this kind of chip now, and Liu Hai has bought various top journals and papers in the world.

Liu Hai has been paying attention to this project since the past two years. Of course, at this stage, it seems that ARM chips do not have a wider market range than Intel chips.

ARM chips rose to prominence after the advent of mobile communications. Before that, Intel had never taken this little brother seriously.

Liu Hai remembered that Intel and this company exchanged patents with each other. This was actually a last resort, because the application range of mobile chips was too wide.

Moreover, in this era, all major companies were tinkering with their own RISC architectures. For example, IBM's POWER architecture, HP's PA-RISC architecture, SUN's SPARC architecture, and DEC's Alpha architecture being developed.

The ultimate success of ARM is the market direction of its embedded applications.

Of course, this will be discussed later.

"We must speed up our pace. Although this chip seems to have various shortcomings now, it is indeed the first chip developed, designed and manufactured by our country." Liu Hai raised this chip to such a height in one sentence.

Ni Nan patted his skinny chest and said, "Boss, don't worry, our entire laboratory is working hard, and we should be able to submit a perfect answer sheet before the end of the year."

"As long as you can do it by the end of the year, the bonus will not be small." Liu Hai was also very happy. Fenghuo Technology Company has invested too much.

Fortunately, I have a good ability to make money, otherwise, if the country were to carry out such a large project, I am afraid there would be many obstacles.

Some people say why the country does not carry out such a project?

A country faces all aspects. Our country is vast and rich in resources, and the land in most places is not very good, so we have to solve the problems of food, clothing, housing and transportation for the general public.

Liu Hai's Fenghuo Technology Company is expected to invest 20 billion US dollars or even more within 10 years.

A country is not a country of one person. Even if a leader is optimistic about the development of the semiconductor field, it is impossible to say that he will spend tens of billions of dollars on this project, because success is unknown.

Unlike Liu Hai, who has foresight and knows the general direction of all things, he dares to invest so much.

If tens of billions of dollars are invested in the semiconductor field, what about other fields?

Although our country is much better now than in history, there is no time when a country does not lack money.

Many times when we look back at history, we regret why we did not continue to invest in this field?

Because from the perspective of the time, there were too many places to spend money. In history, let alone semiconductors, even the navy did not have enough money to build ships. In the 1990s, tanks were fixed on the deck.

When this chip came out, combined with its own lithium battery, a new type of mobile phone was immediately developed.

In fact, mobile phones have been running for a long time. Germany began to use mobile phones for communication during World War II. Of course, it was very large at that time.

In 1956, the first fully automatic mobile phone operation system (MTA) was built by Ericsson in Sweden, but at that time a mobile phone weighed 40 kilograms.

1TB, due to the use of transistors, is only 9 kilograms.

In 1970, mobile phones can finally roam freely between base stations.

In 1971, the first successful commercial mobile phone network was built in Finland.

In 1973, Bell Labs successfully tested the prototype of the mobile phone DynaTAC.

In 1978, Bell Labs built the first experimental commercial mobile phone network in Chicago.

This year, Nokia released their first mobile phone, Mobira Senator. The FCC also approved the Advanced Mobile Phone Service (AMPS) based on analog signals, with a frequency band between 824-894 MHz. The next year, Motorola was unwilling to lag behind and launched the first mobile phone product in the United States, DynaTAC 8000x.

In 1991, Nokia achieved the first commercial GSM communication.

In 1993, the first text message!

Liu Hai was excited when he thought of these, because these mobile phones will all use their own lithium batteries, lithium iron phosphate ternary lithium batteries, and now my country is far ahead of the world.

What makes Liu Hai even more excited is that when this chip comes out, he will launch a mobile phone that is lighter and has a longer battery life than Motorola Nokia.

Although the first analog mobile phone was not manufactured by itself, the first digital communication mobile phone was definitely manufactured by itself.

Of course, the subsequent lithium battery production will be licensed to other countries in the world. Liu Hai is not a person who eats alone.

Because those who eat alone often end up on the wrong path.

Only after the mobile phone industry explodes will Liu Hai authorize other companies to produce lithium batteries, so that he can get the highest licensing fee.

Xiao Benzi has laid out hydrogen energy everywhere, and in the end, others think that he has taken the wrong development path.

In fact, it is not that he has taken the wrong path, but that everyone saw his greed and decided not to follow his path and let him play alone.

If Liu Hai holds the patents related to lithium batteries, believe it or not, Europe and the Western group will not use your lithium batteries directly, and may even say that your lithium batteries are dangerous and prohibited from use.

There is nothing that those people can't do, after all, it is a fact that lithium batteries are dangerous.

At that time, I will authorize the technology to the factories in their country, and these factory owners will naturally speak for me when they have benefits.

"How about the fiber optic network test?" Liu Hai asked another question.

Fiber optic networks are not to be laid out immediately, but to be tested first.

Because there are no large-scale fiber optic network operations so far, only some small experimental institutions in Silicon Valley have such experimental networks.

"The progress is a bit slow, mainly because there are too many problems to be solved. In fact, I personally think that the current cable network has certain advantages." Ni Nan gritted his teeth and said his thoughts, mainly because the fiber optic network test took a lot of time.

"Take your time, there is no rush." ​​After all, this is the first time in the world to do this, so there are definitely difficulties, because there is a big gap between small-scale testing and large-scale application.

Because now the design must be based on experiments, such as how many main optical fibers and how much volume are needed, otherwise the demand will rise in the future and the capacity will have to be expanded again in two or three years.
