", didn't you say you're going to use Starstone as a CPU, why do you want to buy a Xeon processor?"

Chen Xin sat in front of the computer, looking for a suitable CPU according to the requirements of the steel hammer.

The steel hammer held the star stone, and the sunlight shone through the window and shone on the star stone, and the star stone was still blue and clear, pure and clear.

Instead of answering, it asked, "Old Bean, do you know the difference between the human brain and the computer?"

Chen Xin frowned and thought for a moment, and said seriously: "The human brain is a product of evolution in nature and is biological, while the computer is a product of human brain design, not biological. Also, from the point of view of physical structure, there are 14 billion neurons in the human brain, and each neuron has 10,000 synapses, which is equivalent to changing to transistors, that is, there are 140 trillion, and even the current Core 2 only has less than 300 million transistors. ”

Gangyi stroked his palms and smiled: "Lao Dou, what you said is right, more importantly, compared to computers, the human brain or the brain of any intelligent life can naturally produce thoughts, feelings, thinking and other psychological processes, and the wisdom and thoughts produced by the human brain are unlimited." The computer is inseparable from the pre-set program, and what is not in the program will not be consciously generated. There are no programs, computers are just electronic components. Not to mention the higher functions of self-learning, observation, understanding, feelings, personality, etc. ”

Chen Xin was stunned and said, "You mean, Xingshi can be like a human brain?"

Gangyi nodded, and then shook his head and said: "Xingshi represents the ultimate of artificial intelligence, it can imitate ninety-nine percent of the functions of the human brain, the only flaw is that there is no imagination, you know, no matter which civilization, innovation and imagination are the source of civilization progress." ”

Chen Xin asked, "Then what should we do?"

"Although I can't make a robot like the source now, I will re-implant a piece of primary artificial intelligence code in the star stone, an important feature of it is that it can grow itself, it has its own goal orientation, it has a basic goal at different stages of its growth, and with this goal as the center, it is decomposed into smaller or shorter goals in different environments and different situations, and then decomposes until it becomes a specific action." It then uses these goals as a basis to test the correctness of its own information processing results. ”

"This code has no other source of instructions than oneself, just like people, if a person can only act according to other people's instructions, then his life must be very bad. The code always follows the principles of cybernetics when running, constantly checking whether the tasks it runs, the results of these tasks, and the control commands issued based on these results meet the requirements of the current goal, and if there is any deviation, it is immediately corrected, and if possible, it is retried, and then checked, and so on until the goal is reached. It will sort and classify the received information, distinguish the importance of information, process different information, constantly enrich its knowledge base and experience base, and actively expand its own functions......"

The steel hammer babbled a lot, and Zuihou said: "Lao Dou, these processors you bought will be used as a computing tool for the Xingshi code, and the Xingshi code will coordinate the processing of data between various nodes in the center, and provide some computing power when the processor cannot meet the computing needs." However, you have to be mentally prepared that it takes a long time to cultivate artificial intelligence, and it will take at least hundreds of years to grow to the height of the source. ”

Chen Xin was dumbfounded when he heard this, he thought that the steel hammer would make a supercomputer at most, but he didn't expect it to directly engage in artificial intelligence.

As soon as he thought of the meaning behind this project, Chen Xin became excited, rubbed his hands and said: "Steel hammer, then hurry up, which processor do you think is more suitable for us to use?"

pointed to the LCD screen of the computer and said: "Just it, buy a hundred first, the price is also right, I will deal with it after I get it, it should be enough for the time being." ”

The steel hammer is selected by Xeon (Xeon) E3-1225 processor: four cores, four threads, the main frequency is 3.1GHz, the maximum dynamic acceleration is 3.4GHz, the L3 cache is 8MB, and the official price is 194 US dollars, which is 1470 yuan.

Xeon is a Pentium microprocessor produced by Intel, and it has been used in the "middle range" of enterprise servers and workstations. Up to eight Xeon processors can share a 100MHz bus for multiplexing on Intel's server boards.

In recent years, Xeon is replacing PentiumPro as Intel's main enterprise microchip. Designed for use on the Internet and for a wide range of data processing services, such as engineering, imaging and multimedia applications that require the rapid transfer of large amounts of data, Xeon is the high-end product of the Pentium production line.

However, the XeonE3-12x5 series selected by is closer to the SandyBridgeCorei7/i5/i3 on the desktop, but the specifications are more powerful and the functional characteristics are more complete: 32nm process manufacturing, LGA1155 package interface, Tcase temperature 72.6°C, thermal design power consumption 95W, dual-channel DDR3-1333/1066 memory, maximum capacity 32GB, maximum bandwidth 21GB/ and support ECC error checking;Integrated graphics core HDGraphicsP3000, dynamic frequency 850-1300MHz, support QuickSync video transcoding, InTRU3D stereoscopic, FDI flexible display output, ClearVideoHD HD video decoding, dual-screen output, etc.;SSE4.1/4.2, AVX instruction set, Hyper-Threading (except E3-1225), TurboBoost2.0 dynamic acceleration jishu, VT-x, VT-d virtualization jishu, TXT trustworthy execution jishu, DBS on-demand switching jishu, TMT temperature control jishu, EDB anti-virus jishu, fast memory access and elastic memory access jishu.

A few days later, Chen Xin spent more than 300,000 yuan to buy Xeon processors, blade server cases, large-capacity memory, motherboards, hard disks, etc.

After the workers moved all the equipment upstairs and filled the living room, Chen Xin sat on the sofa and said to the steel hammer who was eating coins: "Steel hammer, my task is completed, and I will hand it over to you next." ”

The steel hammer tossed a coin and caught it with his mouth, squeaked and chewed, clapped his hands and said, "Okay!"

It directly got up and turned over to the coffee table, unwrapped a Xeon E3-1225 processor, held the processor in the palm of its hand, and the two electronic eyes emitted a strange light to wrap the processor.

Soon, said: "Old Bean, okay!"

Chen Xin took over the Xeon E3-1225 processor that had been treated with steel hammer, and said curiously: "What have you done with steel hammer, it doesn't look like anything has changed on the surface." ”

quacked and laughed, "Old Bean, do you know the quantum Hall anomaly?"

Chen Xin shook his head and said with a puzzled expression: "I know the Hall effect, what is the quantum Hall anomaly?"

The Hall Effect He had learned about electronic circuits when he was an undergraduate, and as for the most cutting-edge technology like the quantum Hall anomaly, Chen Xin had heard of it for the first time.

The so-called Hall effect was discovered by the American physicist Hall in 1879, when the current passes through the conductor perpendicular to the external magnetic field, there will be a potential difference between the two end faces of the conductor perpendicular to the magnetic field and the direction of the current, this phenomenon is the Hall effect. This potential difference is also known as the Hall potential difference.

The Hall effect is particularly important in the application of Jishu, according to the Hall effect of the Hall device, is to use the magnetic field as the working medium, the motion parameters of the object into the form of digital voltage output, so that it has the function of sensing and switching.

So far, Hall devices that are widely used in modern automobiles alone include: signal sensors on distributors, speed sensors in ABS systems, automobile speedometers and odometers, liquid physical quantity detectors, current detection and working status diagnosis of various electrical loads, engine speed and crankshaft angle sensors, various switches, etc.

For example, in automotive ignition systems, designers place Hall sensors in distributors instead of mechanical cut-offs and are used as ignition pulse generators. This Hall-style ignition pulser generates an impulse voltage within a charged semiconductor layer by a speed-varying magnetic field that controls the primary current in the electronic control unit (ECU). Compared with the mechanical shut-off, the Hall ignition pulse generator is wear-free and maintenance-free, can adapt to the harsh working environment, and can accurately control the ignition timing, which can greatly improve the performance of the engine, which has obvious advantages.

In addition, there is a power Hall circuit used as a switch circuit in automobiles, which has the effect of suppressing electromagnetic interference. Many people know that the more automated the car is, the more microelectronic circuits there are, and the more afraid it is of electromagnetic interference. There are many lamps and electrical devices in automobiles, especially headlamps, air conditioning motors and wiper motors with large power, which will generate inrush current when switching, so that the mechanical switch contacts will produce arcs and produce large electromagnetic interference signals. These phenomena can be reduced by using power Hall switching circuits.

Gangyi explained: "Lao Dou, you should know that when we use computers, we will encounter problems such as computer heating, energy loss, and slowing down. This is because the electrons in the chip do not have a specific orbit and collide with each other under normal conditions, resulting in energy loss. The quantum Hall effect, on the other hand, can set a rule for the movement of electrons, allowing them to move forward 'indomitable' on their respective runways, just like a high-end sports car, which normally moves forward in a crowded farmer's market, and under the quantum Hall effect, it can move forward on a highway that 'goes its own way and does not interfere with each other'. ”

"However, the quantum Hall effect normally requires a very strong magnetic field, equivalent to 10 computer-sized magnets, which is not only bulky but also expensive, making it unsuitable for PCs and laptops. The beauty of the quantum anomalous Hall effect is that it does not require any applied magnetic field, and the quantum Hall state can be realized in a zero magnetic field, which is easier to apply to the electronic devices that people need in their daily lives. ”

Chen Xin quickly understood, and immediately looked at the Xeon E3-1225 processor in his hand that had been treated with steel hammer, and asked: "You mean, after your processing, this chip has realized the quantum Hall anomalous effect, and there is almost no heat dissipation when it is running, and the power consumption is very low?"

The steel hammer nodded and added, "And the performance has also improved more than tenfold!"

Chen Xin couldn't help but mutter: "Black technology, real TNND black technology!"
