Building madman

North America.

New York University Computer Laboratory.

A white-haired old man holds a smart card connected to many data lines and calls the elf:

"Ram!"

"Now, what's the matter?"

"I'm hungry."

"What do you want to eat?"

"A pizza."

"Which one would you like to eat?"

"Curry beef."

"You don't seem to like spicy food."

"Yes, you know all of this?"

"Sorry, I have collected your daily information. Although your privacy is involved, you have already signed this agreement before using the Smart Card."

"Oh, I remembered, I talked about this with my wife."

"Then have a curry beef pizza?"

"Yes, Thanks."

"The cost has been deducted from the smart card account, and Huo Dun Security will deliver the food within half an hour, making the meal a pleasant one."

"By the way, Ram, help me contact the governor."

"There is no relevant record in your address book, but I can spend 30 seconds searching for you."

"Thank you."

"The governor's phone number is...Do you want to call?"

"Do not."

The white-haired old man stopped asking questions, turned off the smart card, and picked up a smart phone.

"Harry."

"Ding……"

"I'm hungry."

"Go to eat quickly."

"Harry?"

"Ding……"

"I'm hungry."

"Go to eat quickly."

"Harry, help me contact the governor."

"Sorry, the governor's contact information could not be found."

"Harry."

"Ding……"

"Help me contact my wife."

"Sorry, I can't find the contact information for my wife."

The white-haired old man took a look at the address book and added an A-letter prefix "wife", turned off his smartphone, "monitoring results."

"Report professor, during the period of use, the smart card consumes 326k data, and the smart phone consumes no data."

"Report professor, during the period of use, the Shenlong chip has operated 2,000 times, and the smartphone has operated 140,000 times."

"Report Professor, during use, the Shenlong chip consumes 0.1mAh, and the smartphone chip consumes 3mAh,”

"Report professor, during the period of use, the smart card is activated twice for positioning, and the smart phone has no operation."

"report……"

"The problems are in the number of calculations, power consumption, and artificial intelligence, these three aspects."

"But professor, we have tested all the electronic components, they are all iterative products, very backward."

"Where is the Shenlong chip?"

"Sorry, it is automatically destroyed after disassembly."

"You must find a way to crack it."

"We have purchased 20,000 Smart Cards of various price points, which cost nearly 10 million Franklin, plus scientific research expenses... The Technology Alliance..."

At this time, a scientific researcher suddenly jumped up.

"Professor, new discovery!!!"

"what?"

"I connected it to a ternary computer simulator based on a binary computer, and a bunch of unknown symbols jumped out!"

"Huh? A reaction?"

The white-haired old man hurried forward, watched carefully for a moment, and tried to input bytes, but the computer crashed directly.

"This...I think, I found the root cause!"

"Professor, what do you mean?"

"Ternary!"

"But ternary is not as good as binary."

"Yes, the simpler the algorithm, the faster the calculation speed, the smaller the system data packet, the better the performance, but all this is based on the premise that the semiconductor material remains unchanged. It has been proved mathematically that the most efficient computer system is e System, but this irrational number cannot be realized physically, and the closest to it is ternary system. Therefore, ternary system is more efficient than binary system, but binary system is easier to realize and commercialize. If ternary system appears, and Rapid commercialization is bound to cause a devastating blow to the current industry and ecology."

The white-haired old man picked up a mahjong-sized, ultra-thin black electronic component, "Perhaps, the simple single-chip microcomputer that is ignored by people uses a ternary system, or a new system that exceeds the ternary system and is closer to the e-system. ."

"But, Professor, if you want to achieve this, you must introduce a negative power supply. Change the signal transmission to a set of three wires, or change to multiple types of transistors. The gate circuit is also composed of complementary transistors, and the amount is at least twice that of binary. Although the performance is improved More than twice, but it is necessary to replace semiconductor materials, increase the number of registers, and adjust the structural framework to increase the main frequency, increase the voltage, and increase the power consumption. The results of our test just now show that the power consumption of the Shenlong chip is much lower than that of the smart phone. ."

"No, no, no, Longtian Technology has graphene, which can replace silicon components, they use optoelectronics, distributed storage, everything has changed...wait!"

After the white-haired old man finished speaking, his eyes widened suddenly, "My God, this designer is simply a genius, it's amazing!"

"???" The room is full of top researchers in North America's science and technology circles.

"Everything has changed! Yes, everything has changed! You have to wash away the binary concept in your brain, and rebuild the three-state digital logic, even the Karnaugh map is three-dimensional. Moreover, its most important function is information exchange , IOT communication, and simulation of environmental variables are not complicated calculations, or even too many calculations. This is the main reason why it has only used 2,000 calculations, but smart phones have used it more than 100,000 times."

"Multi-dimensional computer?!"

"Perhaps, maybe not... No, it is limited by the current'digital signal' mode and cannot break through dimensions temporarily. If even the signal channel is replaced with a new three-state digital logic, then all this will be more perfect. But in this way, it seems to have become a quantum computer again, but obviously, the SG device is not a quantum computer..."

After the white-haired old man finished speaking, he fell into deep thought. After a long time, "I seem to have entered a magical world, and can no longer consider binary related matters. Today's topic is here. Go back and look for relevant materials."

"Good professor."

Wait for the researchers to leave.

A Huo Dun held a pizza in his hand, whistling, and rang the laboratory very casually, "Mr. Raphael? Your takeaway."

"Oh, thank you!" The white-haired old man opened the inner door of the laboratory.

Unexpectedly, after putting down the food, Huo Dun did not leave. He forced open the anti-theft iron door, "Mr. Raphael, you and your researcher need to change jobs."

Seeing this scene, the white-haired old man almost stared out, "NONONO! I don't understand what you mean."

"I mean, you know too much!"

"???"

boom……

Holden stuns the white-haired old man, skillfully took out a special SGpad, connected to the laboratory host, adjusted the monitoring, erased the traces of the smart card ordering, disconnected after ten minutes, and then carried the white-haired old man behind his back. Enter the mast security suit, tie your left hand to your left hand, tie your right hand to your right hand, the same is true for your legs, put the safety helmet back to cover the opponent's head, pull up the laboratory safety door, copy your pockets with your hands, and leave with a whistle Here……

………………………………

Approaching New Year's Day, the blink of an eye is about to enter 2002.

The graphene storm that occurred two years ago still deeply affects the parent planet's science and technology field, both for good and for bad.

Fortunately, with graphene, a new bug-level material, and relying on optoelectronic communication technology, China has shortened the gap between itself and the science and technology alliance to five years without precedent.

The bad thing is that our side is pressing harder and harder, and the technology alliance that implements the "toothpaste squeeze" strategy has a lot of assets, such as 3G mobile communication technology.

As a result, the gap between the two sides widened again.

It's not that Longtian doesn't work hard, but that the field of science and technology is too extensive, far more than just small chips.

Take the Dongshan industrial chain promoted by Tiancheng as an example.

Zigbee is currently used.

It is a wireless network technology that uses optical fiber communication to build large-scale wifi base stations, intersperses and overlaps each other, and builds a wireless network technology.

When people leave this area, the network is disconnected, or they use a 2g cellular network with a speed of only 20k, or turn on the on-board GLONASS augmentation system to extract a one-meter-long satellite antenna to receive the satellite network.

The download speed of Zigbee technology theory can reach 30M, but because the base station belongs to a shared network, as the number of users increases, network channels like IP are gradually filled. The download speed of the Zigbee network is only 300K, or in other words, a fiber can only support Used by a hundred users.

Thanks to Daoyi’s invented smart switching, smart connection, and smart distribution technology, squares, supermarkets, and office buildings are equipped with optical cables, optical fibers, and the number of base stations, which temporarily can meet the use of Dongshan SG equipment and smart card, a total of 50 million users .

However, with the replacement of 2.5G overseas, the popularization of 3G, and the increase of download speed to 2M, Zigbee wireless network communication, which was far ahead two years ago, has begun to fall behind.

If you do not find a solution, let alone your own smart card is facing elimination, even remote control technology will be far away.

the most important is.

The Shenlong chip needs to exchange a large amount of data with the Shiguang machine's mother body to obtain "intelligence". The more functions, the higher the requirements for network speed.

In 2002, the smart card will add camera, camera translation, camera identification, the most basic AR mini games, etc., plus the use of a ternary-like Shenlong system with different algorithms, resulting in large data packets and data transmissions. different.

For example, for the same thousand-word article, the technology alliance only needs 1k traffic. After compression, it may not use 1k, but it needs 10k traffic...

Not bad, but it involves data exchange, noun annotations, article sources, related knowledge, and so on.

The 300k network speed obviously cannot meet the subsequent usage with a large number of graphics and text.

If you want to stay ahead, you must surpass the 2M network speed of 3G mobile communication technology.

Therefore, Ge Xiaotian thought of a satellite network with a download speed of 15M.

Launch enhanced satellites and make reasonable allocations, such as reducing the uplink channel (reducing the upload speed) and increasing the downlink channel (increasing the download speed). The network speed of the smart card may be able to exceed 20M.

However, to use a satellite network, you need to be equipped with a one-meter-long satellite antenna, working at home, or car-mounted office, it is better to put a small pot cover to transfer, but personal use...

Have you seen Teletubbies?!

In addition, 6,900 satellites form a network star chain, which is impossible to complete in a short time, and Ge Xiaotian does not have that much money.

The reason for proposing this concept is to launch a few first to see if the satellite network can be integrated into the Zigbee base station and upgraded to a new Zigbee with cellular+satellite network+wifi+NFC+Bluetooth technology, and finally reduce the delay to milliseconds Level, and then down to the microsecond level.

In fact, Bingxiong can also launch, but the network involves frequency band issues. If you want to use it in China, you still have to apply. It's better to get it all at home.

In addition, Daoyi underestimated the strength of the Science and Technology Alliance. In the past two years, some people have touched on some information about the Shenlong chip. If you further explore the e-system, think of the pi, and then contact the gossip...

The Shenlong system was cracked.

In the field of science, by chance, nothing is impossible.

Therefore, it is necessary to speed up the'information exchange'. When overseas scientists explore this field, they can bring the other party to work as soon as possible.

After all, some top scientists far surpass them in a single field.

In other words, Daoyi they need to absorb top knowledge in various fields, break through the system level after fusion, and activate the five-level technology tree...

In summary, increasing internet speed is related to remote control, smart card use, capturing overseas scientists to improve one's own strength, etc. It is imperative!

…………………………

The Nine Institutes know that 3G is popularizing overseas and understand the dilemma that ZigBee faces, but they never thought that Tiancheng would launch so many satellites.

"Six thousand nine hundred? One a day, you will shoot for 18 years!"

"Why one a day?"

"Otherwise? Shot to death three times a week?"

"Why can't we have N or dozens of them at once? Hundreds?"

"Impossible. After the satellite enters the orbit, it needs to be adjusted and observed for six to eight hours. The staff's energy is limited. The staff can continue to operate for up to 24 hours, which is three arrows. If the staff is replaced midway, one is not so much. Manpower, second, it is impossible to determine whether the two parties can be familiar with the same set of data changes after the handover. Third, you don’t know the common problem of your Shiguang machine? You must rest for six hours after continuous use for twenty-four hours to avoid laser burning of the mosaic graphene The motherboard of the chip."

"The motherboard problem is being dealt with. We have found a topological insulator, which can be a good substitute for the motherboard."

"What the hell?"

"Topological insulator, a new type of material with internal insulation and charge movement on the surface. If graphene is irradiated with mid-infrared laser to create an artificial dynamic band gap, this is a topological insulator. In this way, graphene chips do not need to be embedded in The motherboard directly forms an integrated circuit. From then on, we can convert optical signals into electrical signals and convert electrical signals into optical signals as we like. Moreover, electronic components can also be multi-layered and irregularly-shaped, including the square The batteries can be made into various shapes to facilitate the reduction of the size of electronic devices."

"I don't understand, can you be professional?"

"It probably means that under normal conditions, graphene behaves as a normal conductor, voltage is applied to it, and current passes through it. Based on its own characteristics, it can be made into a graphene chip. But if a piece of graphene is placed on it In a vertical magnetic field, the characteristics of graphene will change and become a topological insulator. The current will only run along the edge of the graphene sheet, and the other parts will become insulators. At this time, the current will only follow one direction according to the direction of the magnetic field. Moving forward, the quantum Hall effect appears. If a strong magnetic field level with the place where the graphene is placed is added, the properties of the graphene will change again, and the electrons can still only travel along the edge of the graphene, but the direction of travel changes from one-way to two-way , And the number of specific directions is determined by the direction of the electron spin, that is, the quantum spin Hall effect."

"Still don't understand."

"In other words, this experiment confirmed that a single sheet of graphene is selective to spin electrons and can control the direction of electrons and the state of electricity. In other words, the topological insulator evolved from graphene can make a quantum computer! "

"thank you!"

"???"

Ge Xiaotian reacted instantly and was fooled, "Can you understand?"

The Jiu Institute shook his head quickly, "No, I don't understand."

"take money!"

"I really don't understand. I am only responsible for the remote control system. Really, I don't understand high-tech materials at all."

"Stop playing, stop doing it, go home and farm!"

"Don't don't don't, why are you so extreme, you are such a big industry, if you say you lose it, you lose it?"

"Why do you want so much if you don't bring it to life or death?"

"..."

Nine Institutes pouted. In the eyes of overseas people, this money is losing money, but in the eyes of superiors, this girl is the "world peace" in the commercial field, the Oriental Super Buffet + Super Soros, if you really don't play, Well, the problem is quite big.

"Wait, I'll exchange something for you."

"Quantum computers are priceless."

"You are only talking about theory."

"That's also priceless."

"Okay, I must come up with an equivalent technology. By the way, don't you want to launch 6,900 satellites, why?"

"Reduce latency, increase speed and high-speed mobility."

"Six thousand nine hundred satellites, calculated as three stars with one arrow..."

"We can achieve 20 stars with one arrow."

"Okay, then the calculation is based on one arrow and twenty stars."

The Nine Institute nodded, not surprising to the new breakthrough of the Tiancheng Aerospace Department. After all, Tiancheng Secondary School had already excluded the fourth batch of students from going to the Ice Bear Aerospace Department for further study. It is estimated that the Ice Bear did not know what happened during the period.

Moreover, Huaxia currently does not use the technology of one arrow and twenty stars, and when it is needed, Tiancheng estimates that it has developed a hundred stars with one arrow, and will definitely throw one arrow and twenty stars to its Aerospace Department.

Thinking about it, the Nine Institutes calculated:

"Twenty stars with one arrow, 345 rockets, about 10 billion Franklin. Six thousand and nine hundred satellites, about 140 billion Franklin. Including transportation, insurance, etc., I This plan can save you at least 200 billion Franklin."

"If the network star chain project can be banned, its own value is indeed comparable to quantum computers."

"No, it can lead the global communication for N times, but we can't use it at the moment, and we don't need it. Also, even if you can build a network star chain, but the satellite signal receiver is one meter long, how can you reduce it to a personal terminal? ? Overhead antenna?"

"..." Ge Xiaotian thought of this question before.

"So, my project has its own value beyond quantum computers."

"Excessive, do you want me to post another technique?"

"No, I just remind you that it is very valuable."

"Well, let's talk about it."

"Actually, it is also called the Purple Bee."

"..."

Ge Xiaotian was expressionless.

"Don’t get me wrong, it’s different from the Zigbee technology that uses fiber optic networks to switch to a large wifi mode in your home. It is an ultra-wideband wireless communication technology implemented by countless terrestrial base stations. It should be called 3G, but its essence is different from the 3G developed overseas. ."

"4G?"

"I still have 5G."

"Ok?"

"Hmm?"

"Do you know 5G?"

The Nine Institute laughed and scolded: "I still know 6G, 7G, and 8G."

"hiss……"

"I'm kidding, look at how serious you are, stop making trouble, talk about business."

"..."

"It is called visible light communication, which refers to the use of light in the visible light band as an information carrier to directly transmit optical signals in the air. This is our leading technology and a top-secret project."

"Didn't you choose electronic technology? How come you start to use optoelectronic technology like us?"

"Your family has such a small number of scientific researchers. It has just risen in the past two years. Can it be compared with the hundreds of thousands of scientific researchers of the China Aerospace Department and have decades of accumulation? Although we choose electronic technology, optoelectronic technology It hasn't fallen. This is called balanced development."

"Ok."

It seems that the monks will continue to be brutal.

The Nine Institute took out the Shiguangji notebook, turned on the NFC function, adjusted the data without encryption, and shared it with the Shenlong account.

Ge Xiaotian opened his Shiguangji notebook and read it carefully...

'Di, activate the initial communication technology of Optoelectronics Technology...'

'Dip, the redemption list has been updated.'

'Visible light communication technology uses fluorescent lights or light-emitting diodes to transmit information that is invisible to the naked eye. Connect the high-speed network cable device to the lighting device and plug in the power plug to use.'

'The network system made with this technology can cover the range of indoor lighting. The computer does not need to be connected by wires. As long as the indoor lighting is illuminated, it can download and upload high-definition images and animations for a long time.'

'The system also has extremely high security. Use curtains to block the light, so the information will not leak to the outside, and the use of multiple computers at the same time will not affect the communication speed. Because it does not use radio waves to communicate, it is sensitive to electromagnetic signals. , You can use the system freely.'

'This technology continues to improve with the growth of the technology tree, and the current shared network speed limit is 150M.'

'You activate the 1W, LED lamp beads controlled by the graphene microchip, which can share 10 users, the average internet speed is 20M, and the exchange requirement: 5 rare resources.'

'You activate the 10W, LED lamp beads controlled by the graphene microchip, which can share 100 users, the average internet speed is 20M, and the exchange requirement: 10 rare resources...'

'You activated the 100W, LED lamp bead controlled by the alternate day and night graphene microchip...'

'You have activated...200W, LED lamp beads...'

'You activated... 400W, LED lamp beads composed of two groups of 200W...'

'You activated the 10mW laser...'

'You activated the 100mW laser...'

'You activate...'

'...'

'You have activated the visible light receiver...'

'You have activated the base station where visible light communication and Zigbee merge...'

Ge Xiaotian glanced at hundreds of different types of "visible light" LED lights, laser lights, laser lights, etc., ranging from 20M network speeds to 150M network speeds, and suddenly had a headache.

It's easy to say indoors, but how do you use a large two-legged mechanical vehicle in the wilderness?

Do you want to use a helicopter to put lights in the air and make your debut?!

Or in other words, point and run with a laser...

Wait, laser guidance?

'It seems that the principle is similar.'

Unfortunately, it can only be exchanged from the system at present, and it will take some time for them to research the actual product.

Another is that the use of visible light receivers will eliminate existing SG equipment and smart cards.

This is obviously a bit unrealistic. It can only transition slowly from laboratories, industries, enterprises, schools, shopping malls... in order.

Ge Xiaotian took a deep breath, lit a cigarette, and looked at the Jiu Institute, "Master, did you know that there is a way of communication that descends from the sky in this world!"

"Nonsense, isn't satellite communications just falling from the sky?"

"No, it's a beam of light, falling from the sky, instantly projecting hundreds of gigabytes of data."

"..."

"Besides, it can also be charged wirelessly. Think about it. You are running around on the battlefield wearing a mechanical exoskeleton. Suddenly you run out of electricity, unable to charge quickly, have no spare batteries, and there is no nearby map pack and the latest combat instructions. What should you do? "

"How to do?"

"Outer space satellites, or space shuttles parked in outer space, will come to you with a beam of'visible light', hoo...Ballala little demon fairy transforms, no, it is full of electricity, and the map package is also passed over."

"So dazzling, I was bombarded to death by enemy missiles."

"..."

"Don't talk nonsense, just talk about business. Visible light communication only solves the terminal transmission problem. You also need to develop optical fibers and cables that match it with Weihua. Otherwise, the pumps and nozzles will be strengthened, and the water pipes will still be so thick. "

"Right."

"If the transmission channel is adjusted to conform to the e-like system data, this is not a small investment. Not to mention laying the whole country, just laying Dongshan, it will need tens of billions.

"Wei Hua has made a lot of money in the past two years."

"You don't pay for your project?"

"You want me to control communications?"

"..."

The Jiu Institute suddenly felt pain in the teeth, "The key is, I take out the technology, and then help you lay the optical cable?"

'You have to help me study quantum computers!'

Ge Xiaotian thought about it carefully.

In fact, he has long known that he understands computers and technology materials.

The reason for deliberately'leaking' quantum computer theory is that Daoyi and they have no knowledge in this area, so that the nine research institutes produced samples and activated them.

And, with a technology that is of little value to oneself, in exchange for the much-needed "visible light" communication, how to look at it and how to make money.

The military has been leading the civilian use for 30 years, and there are North American spies from the outside world. The nine things that can be taken out can be considered as heart-to-heart.

Besides, it mainly focuses on optoelectronic technology, and there must be better performance optical cables and optical fibers. This thing uses plexiglass fiber or all-plastic optical fiber. The cost is as low as one yuan and tens of meters.

"Well, I voted for this project, and provide enough optical cables and optical fibers for free."

"So proud?"

"if not?"

"Whenever you are proud, it means that you have made a lot of money again. What happened today...isn't something wrong?"

"No, you think too much, so what? It will be New Year's Day in two days. If there is something in Dongshan, I will go back first."

"Wait, send me the quantum computer theory!"

"Oh, yes, I almost forgot."

"..."
