Build Madness

North America.

NYU computer lab.

A white-haired old man held a smart card connected to many data lines, and called the elf:

"Ram!"

"Here, what's the matter?"

"I'm hungry."

"What do you want to eat?"

"Have a pizza."

"Which would you like to eat?"

"Curry beef."

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

"Yes, you know all this?"

"Sorry, I collected your daily information. Although your privacy is involved, you have already signed an agreement in this regard before using the smart card."

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

"How about a beef curry pizza?"

"Yes, Thanks."

"The fee has been deducted from the smart card account. Huo Dun Security will deliver the food within half an hour. Enjoy your meal."

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

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

"Thanks."

"Did the Governor's call to...?"

"No."

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

"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 cannot be found."

"Harry."

"Ding……"

"Help me contact my wife."

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

The white-haired old man glanced at the address book, there was an extra "wife" prefixed with the letter A, turned off the smartphone, "monitoring results."

"Professor report, during the use period, the smart card consumes 326k traffic, and the smartphone does not consume."

"Professor, during the period of use, the DPCA chip performs 2,000 calculations, and the smartphone performs 140,000 calculations."

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

"Professor report, during the period of use, the smart card has turned on the positioning twice, and the smartphone has no operation."

"Report……"

"The problem arises in three aspects: the number of calculations, power consumption, and artificial intelligence."

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

"Where's the Shenlong chip?"

"Sorry, it will be automatically destroyed after disassembly."

"A solution must be found."

"We have already purchased 20,000 Smart Cards at various prices, costing nearly 10 million Franklins, plus scientific research expenses...the Science and Technology Alliance..."

At this time, a researcher suddenly jumped up.

"Professor, new discovery!!!"

"What?"

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

"Huh? Did you respond?"

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

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

"Professor, what do you mean?"

"Trinary system!"

"But ternary is not as good as binary."

"Yes, the simpler the algorithm, the faster the calculation speed, and the smaller the system data package, the better the performance, but all of this is based on the premise that the semiconductor material remains unchanged. Mathematics has proved that the most efficient computer system is e base, but this irrational number cannot be realized physically, and the closest to it is the ternary system. Therefore, the ternary system is more efficient than the binary system, but the binary system is easier to realize and easier to commercialize. If the ternary system appears, and Rapid commercialization will inevitably 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 has been ignored by people uses the ternary system, or a new system that surpasses the ternary system and is closer to the e-ary system." .”

"However, professor, to achieve this, we must introduce a negative power supply, change the signal transmission to a set of three wires, or change it to multiple types of transistors, and the gate circuit is also composed of complementary transistors, the consumption is at least twice that of binary, although the performance is improved More than twice as much, but it is necessary to replace semiconductor materials, increase the number of temporary registers, and adjust the structural framework to increase the main frequency, increase the voltage, and increase power consumption. The results of our test just now show that the power consumption of the Shenlong chip is far lower than that of a smartphone. .”

"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 top researchers in the North American scientific and technological circles in the room were all confused.

"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. And, its most important function is information exchange , Internet of Things communication, and simulated environmental variables are not complicated calculations, and even do not require too many calculations, which is the main reason why it only used two thousand calculations just now, while the smartphone used hundreds of thousands of times."

"Multi-dimensional computer?!"

"Maybe, maybe not... No, it is limited by the current 'digital signal' mode, and it cannot break through the dimension for the time being. If even the signal channel is replaced with a brand-new three-state digital logic, then all this will be more perfect. Only But in this way, it seems to be 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 I can no longer think about binary related things. This is the end of today's topic. Go back and look for relevant materials."

"Good professor."

Wait for the researchers to leave.

A Huo Dun held a pizza in his hand, whistled, and rang the laboratory very casually, "Mr. Rafael? 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, and abruptly opened 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, "NONONO! I don't understand what you mean."

"I mean, you know too much!"

"???"

boom……

Horton stunned the white-haired old man, skillfully took out the special SG pad, connected to the laboratory host, adjusted the monitoring, erased the smart card ordering traces, disconnected after ten minutes, and then carried the white-haired old man behind his back. Put on a fat security suit, tie your left hand to your left hand, and your right hand to your right hand. The same is true for both legs. Put the safety helmet back to cover the other party's head, and pull the laboratory safety door. With both hands in your pocket, whistle leave here……

……………………………

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

The graphene storm that happened two years ago still deeply affects the field of mother star technology, both good and bad.

The good thing is that with graphene, a bug-level new material, and relying on photoelectric communication technology, Huaxia shortened the gap between itself and the Science and Technology Alliance to five years unprecedentedly.

The bad thing is that our own side is pressing every step of the way, so that the technology alliance implementing the strategy of "squeezing toothpaste" has a lot of resources, such as 3G mobile communication technology.

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

It's not that Long Tian doesn't work hard, but that the field of technology is too broad, far more than just a small chip.

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

Currently using Zigbee.

It is a wireless network technology constructed by using optical fiber communication to establish large-scale wifi base stations, interspersed with each other, and superimposed.

When people leave this area, the network is disconnected, or they use the 2G cellular network with a network speed of only 20k, or turn on the vehicle-mounted GLONASS enhancement system, and pull out a one-meter-long satellite antenna to receive the satellite network.

The theoretical download speed of Zigbee technology can reach 30M, but because the base station belongs to a shared network, as the number of users increases, the network channel similar to IP is gradually filled, and the download speed of Zigbee network is only 300K, or in other words, one optical fiber can only support shared by one hundred users.

Thanks to Daoyi's invention of smart switching, smart connection, and smart distribution technologies, the number of optical cables, optical fibers, and base stations equipped with plazas, supermarkets, and office buildings can temporarily meet the needs of Dongshan SG equipment and smart cards, a total of 50 million users. .

However, as 2.5G is replaced overseas, 3G is popularized, and the download speed is increased to 2M, Zigbee wireless network communication, which was far ahead two years ago, has begun to lag behind.

If you don’t find a solution, not to mention that your own smart card is facing elimination, even the remote control technology will be left far behind.

the most important is.

The Shenlong chip needs to exchange a large amount of data with the Shiguang machine matrix to obtain "smartness". The more functions, the higher the requirements for network speed.

In 2002, the smart card will add camera, camera translation, camera recognition, the most basic AR mini-game, etc. In addition, our own side uses a ternary-like Shenlong system with different algorithms, resulting in large differences in data packets and data transmission. different.

For example, for the same 1,000-character article, the Science and Technology Alliance only needs 1k traffic. After compression, it may not use 1k, but our side needs 10k traffic...

It's not bad, but it involves data exchange, noun annotations, article sources, related knowledge, and so on.

The network speed of 300k is obviously unable to meet the subsequent usage with a large number of graphics and texts.

If you want to stay ahead, you must go beyond 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), increasing the downlink channel (increasing the download speed), and the network speed of the smart card may be able to exceed 20M.

However, to use the satellite network, you need to be equipped with a one-meter-long satellite antenna. It’s okay to work at home or in a car. You can transfer it with a small pot cover, but for personal use...

Have you seen the Teletubbies? !

Moreover, 6,900 satellites form a network star chain, which is impossible to complete in a short period of time, and Ge Xiaotian does not have so much money.

The reason why I proposed this concept is that I just want to launch a few first to see if I can integrate the satellite network into the Zigbee base station and upgrade to a new Zigbee with technologies such as cellular + satellite network + wifi + NFC + Bluetooth, and finally reduce the delay to milliseconds. level, and then down to the microsecond level.

In fact, it can also be launched in Ice Bear, but the network involves frequency band issues. If you want to use it in China, you still need to apply. It's better to get it done in China at once.

In addition, Daoyi underestimated the strength of the technology alliance. Two years later, some people have already touched some information on the Shenlong chip. If you further explore the e-base system, think of pi, and then contact the gossip...

The Shenlong system was cracked.

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

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

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

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

To sum up, it is imperative to increase the speed of the Internet, which is related to remote control, the use of smart cards, arresting overseas scientists to improve their own strength, etc.

………………………

Jiu Zhi knew that 3G was being popularized overseas, and understood the dilemma that Zigbee was facing, but they never thought that Tiancheng would launch so many satellites.

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

"Why take one a day?"

"Otherwise? Three pills a week, shot to death?"

"Why can't it be N at a time, dozens? Hundreds?"

"Impossible. After the satellite enters orbit, it needs to be adjusted and observed for six to eight hours. The staff has limited energy and can operate continuously for 24 hours at most, that is, three arrows with one arrow. If the staff is replaced midway, there are not so many Second, it is uncertain whether the two parties can be familiar with the same set of data changes after the handover. Third, you don’t know about the common problem of your Shiguang machine? After continuous use for 24 hours, you must rest for six hours to prevent the laser from burning the inlaid graphene. chip's motherboard."

"The motherboard problem is being dealt with, and we have discovered a topological insulator, which can be a good replacement 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 a mid-infrared laser to create an artificial dynamic band gap, it 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 electrical signals into optical signals as we like. Moreover, electronic components can also be arranged in multi-layer and special-shaped layouts, including four-square The battery can be made into various shapes, which is convenient for reducing the size of electronic equipment.”

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

"Probably means that under normal conditions, graphene behaves as a normal conductor. When a voltage is applied to it, 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 in 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 Going forward, showing the quantum Hall effect. If you add another strong magnetic field at the level of where the graphene is placed, the properties of graphene will change again, and electrons can still only run along the edge of 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."

"That is to say, this experiment confirms that single-sheet graphene is selective for spin electrons, and can control the direction of electron movement and electrification state, or in other words, topological insulators evolved from graphene can create quantum computers! "

"thank you!"

"???"

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

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

"take money!"

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

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

"Don't, don't, why are you so extreme, you have such a big fortune, you can lose it if you want to lose it?"

"If you don't bring it with you when you are born, if you don't take it with you when you die, why do you need so much?"

"..."

Jiusuo curled his lips, in the eyes of overseas people, this product is at the bottom of the sky, but in the eyes of the superiors, this is the "world peace" in the business field, the Eastern Super Buffett + Super Soros, if you really don't play, Well, the problem is quite big.

"Wait, I'll give you something good in exchange."

"Quantum computers are priceless."

"What you're talking about is just a theory."

"That's also priceless."

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

"Reduced latency, increased speed and high-speed mobility."

"Six thousand nine hundred satellites, based on the calculation of three stars with one arrow..."

"We can achieve twenty stars with one arrow."

"Okay, then calculate according to twenty stars per arrow."

Nine Institutes nodded, not surprised by the new breakthrough of Tiancheng Aerospace Department, after all, Tiancheng Technical Secondary School has sent the fourth batch of students to Ice Bear Aerospace Department for further study, and Ice Bear himself probably doesn't know what happened during the period.

Moreover, Huaxia currently does not use the technology of twenty stars per arrow, and when it is needed, Tian Cheng probably has researched a hundred stars per arrow, and will definitely throw twenty stars per arrow to his aerospace department.

Thinking about it, Jiusuo calculated:

"Twenty satellites for one arrow, 345 rockets are needed, about 10 billion Franklins. 6,900 satellites, about 140 billion Franklins. Counting transportation costs, insurance fees, etc., we This plan can save you at least 200 billion Franklin."

"If the Network Starlink project can be banned, its own value is indeed comparable to that of a quantum computer."

"No, it can lead the global communication by N eras, but we can't use it now, and we can't use it. Moreover, even if you can build a network star chain, but the satellite signal receiver is one meter long, how can you shrink it to a personal terminal? ? Antenna above the head?"

"..." Ge Xiaotian thought about this problem before.

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

"It's too much, do you still want me to post another technology?"

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

"Well, tell me then."

"Actually, it's also called Zigbee."

"..."

Ge Xiaotian was expressionless.

"Don't get me wrong, it's not the same as the Zigbee technology that uses the optical fiber network in your home to convert to a large-scale wifi mode. It is an ultra-bandwidth wireless communication technology realized by countless land base stations. It should be called 3G, but it is essentially different from the 3G developed overseas. .”

"4G?"

"I still have 5G."

"Um?"

"Huh huh?"

"You know 5G?"

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

"hiss……"

"I'm just kidding, look at your serious stupidity, don't make trouble, let's talk about business."

"..."

"It's 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 in China, and it is also a top-secret project."

"Didn't you choose electronic technology? Why are you starting to use optoelectronic technology like us?"

"Your family has only a few scientific research personnel, and it has just emerged in the past two years. Can it be compared with the hundreds of thousands of scientific research personnel of the China Aerospace Department, and has decades of accumulation? Although we choose electronic technology, optoelectronic technology This is called balanced development.”

"All right."

It seems that the monks will continue to be violent.

The Nine Institute took out the Shiguangji notebook, turned on the NFC function, adjusted the data that does not need to be encrypted, and shared it with the Shenlong account.

Ge Xiaotian opened his Shi Guangji notebook and looked through it carefully...

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

'Drip, the redemption list has been updated. '

'Visible light communication technology uses high-speed bright and dark flickering signals invisible to the naked eye emitted by fluorescent lamps or light-emitting diodes to transmit information. Connect the high-speed network cable device to the lighting device and plug it into the power plug to use it. '

'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 data such as high-definition images and animations for a long time. '

'The system is also highly secure. Use curtains to cover the light, so that information will not leak to the outside, and the use of multiple computers at the same time will not affect the communication speed. Since it does not use radio wave communication, departments sensitive to electromagnetic signals , the system is free to use. '

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

'You have activated the 1W, LED lamp bead controlled by the graphene microchip, which can be shared by 10 users, with an average network speed of 20M, exchange requirement: 5 rare resources. '

‘You have activated the 10W and LED lamp beads controlled by the graphene microchip, which can be shared by 100 users, with an average network speed of 20M, exchange requirements: 10 rare resources...’

'You activate a 100W, LED light bead controlled by a day and night graphene microchip...'

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

'You have activated... a 400W, LED bead consisting of two sets 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 are fused...'

Ge Xiaotian glanced at hundreds of kinds of "visible light" LED lights, laser lights, laser lights, etc., ranging from 20M network speed to 150M network speed, and suddenly felt a headache.

Indoors is easy to talk about, but how can a big two-legged mechanical vehicle be used in the wilderness?

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

Or in other words, pointing and running with a laser...

Wait, laser guidance?

'It seems that the principle is similar. '

It's a pity that it can only be exchanged from the system at present. It will take some time for Daoyi and the others to research the actual product.

Another one is that the use of visible light receivers requires the elimination of existing SG equipment and smart cards.

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

Ge Xiaotian took a deep breath, lit a cigarette, and looked at Jiusuo, "Grandpa, do you know that in this world, there is a communication method that descends from the sky!"

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

"No, it's a beam of light that descends from the sky and instantly projects hundreds of gigabytes of data."

"..."

"In addition, it can also be charged wirelessly. Think about it, you are running around on the battlefield wearing a mechanical exoskeleton, and suddenly you run out of power, you can't charge it quickly, you don't have a spare battery, and you don't have a nearby map bag or the latest combat instructions. What should you do? "

"what to do?"

"A satellite in outer space, or a space shuttle parked in outer space, will send a beam of 'visible light' to you, oh... blah blah, little magic fairy transforms, no, the battery is fully charged, and the map package has also been transmitted."

"It's so eye-catching, I've been bombarded to death by enemy missiles."

"..."

"Don't talk nonsense, let's get down to business. Visible light communication only solves the problem of terminal transmission. You also need to develop optical fibers and cables that match it with Weihua. Otherwise, the water pump and nozzle will be strengthened, and the water pipe will still be so thick. There is no use. "

"Right."

"If the transmission channel is adjusted to conform to the e-ary system data, this is not a small investment. Not to mention laying the whole country, just laying Dongshan, it will cost 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?"

"..."

Jiusuo suddenly felt a pain in the teeth, "The key is, I will take out the technology and help you lay the optical cable?"

'You also want to help me research quantum computers! '

Ge Xiaotian thought about it carefully.

In fact, he already knew that the Nine Institutes knew about computers and technical materials.

Deliberately 'leaking' the theory of quantum computers is because Daoyi and the others have no knowledge in this area, so they let the Ninth Research Institute do research, and when they produced samples, they activated it themselves.

Moreover, take a technology that is of little value to oneself in exchange for the urgently needed 'visible light' communication, how to look at it and how to make money.

The military has been ahead of civilian use for 30 years, and the outside world has North American prying eyes. Nine can be taken out, and it can be regarded as empathy.

Besides, the company focuses on optoelectronic technology, so there must be optical cables and optical fibers with better performance, which use plexiglass fibers or all-plastic optical fibers, and the cost is as low as one yuan for dozens of meters.

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

"So proud?"

"if not?"

"Whenever you are arrogant, it means that you have made a lot of money again. Today's matter... Is there something wrong?"

"No, you're thinking too much. Well, it's New Year's Day in two days. I still have something to do in Dongshan, so I'll go back first."

"Wait, send me the quantum computer theory!"

"Oh, yes, almost forgot."

"..."
