Chapter 179 Concerns about Artificial Intelligence

Worries about artificial intelligence have cast a shadow over Fang Zhe's heart. For him, what he needs is a stable weapon, not this kind of mechanical life with intelligence.

In the age of civilization, the famous Professor Nelson gave such a definition of artificial intelligence: "Artificial intelligence is a discipline about knowledge—the science of how to represent knowledge and how to obtain and use knowledge."

And another professor Winston from the Massachusetts Institute of Technology believes: "Artificial intelligence is the study of how to make computers do intelligent work that only humans could do in the past."

These statements reflect the basic ideas and basic content of this mechanical life, artificial intelligence.That is, artificial intelligence is the study of the laws of human intelligence activities, the construction of artificial systems with certain intelligence, and the study of how to make computers complete tasks that required human intelligence in the past, that is, to study how to use computer software and hardware to simulate certain human intelligence. Basic theories, methods and techniques of behavior.

Artificial intelligence is a branch of computer science. Since the 70s, it has been called one of the world's three cutting-edge technologies (space technology, energy technology, artificial intelligence).also
It is considered as one of the three cutting-edge technologies (genetic engineering, nanoscience, artificial intelligence) in the 21st century.This is because it has developed rapidly in the past 30 years, has been widely used in many disciplines, and has achieved fruitful results. Artificial intelligence has gradually become an independent branch, both in theory and practice. a system.

But for the use of machinery, before the arrival of the apocalyptic virus, humans still had no clue, which involved something more complicated.

There is a very strict limit on the life of a machine. Once the machine is damaged internally, there are many places involved and it is difficult to repair.

For artificial intelligence, most of the reasons for their IQ come from learning, and the support of artificial intelligence learning must be inseparable from one thing, that is, the CPU.

The CPU is also the central processing unit. As the computing and control core of the computer system, it is the final execution unit for information processing and program operation. Since the CPU was produced, it has made great progress in logic structure, operating efficiency and function extension.

The central processing unit (CPU) is one of the main devices of an electronic computer and the core component of a computer.

Its function is mainly to interpret computer instructions and process data in computer software. The CPU is the core component in a computer responsible for reading instructions, decoding them, and executing them.

The central processing unit mainly includes two parts, namely the controller and the arithmetic unit, which also include the cache memory and the data and control bus that realize the connection between them.

The three core components of an electronic computer are the CPU, internal memory, and input/output devices.The main functions of the central processing unit are to process instructions, perform operations, control time, and process data.

The von Neumann architecture is the foundation of modern computers.Under this architecture, programs and data are stored uniformly, instructions and data need to be accessed from the same storage space, transmitted via the same bus, and cannot be overlapped.

The arithmetic unit refers to the parts of the computer that perform various arithmetic and logical operations, and the arithmetic logic unit is a part of the central processing core.

However, under the blessing of the "mechanical force" of the civilization rescue system, this rule is completely violated. For Fang Zhe, who lives in the civilized age, there is nothing more weird than this.

It's like releasing the balloon and the balloon is falling down. Under the gravity of the earth's g equal to 10, completing this operation brings weirdness and inconceivableness.

The sword under the blessing of mechanical force completely violates the essence of artificial intelligence, and also violates the essence of machinery. You must know that for human beings, the most proud invention is not the rocket.

Not guns, nor planes, ships, cars, trains, televisions, washing machines
These things are the footprints of step by step. There are chickens and eggs. If it is the greatest invention of human beings, it is the thing that gathers the attention of everyone - the cpu.

When it comes to the manufacture of cpu, the difficulty can be said to be the most on the earth. The natural sand itself already has a very high purity silica mineral. After melting it and removing impurities, it can be smelted with a diameter of 300mm and a weight of 100kg. , Single crystal silicon crystal with a purity of 99.9999%.Afterwards, the columnar crystals are sliced ​​into thin slices with a dicing machine to obtain wafers for further processing.

After that, the metal ions are "bombarded" to the surface of the silicon wafer through a high-energy accelerator to form a doped semiconductor layer, which is ion implantation; and then covered with a layer of Hi-K (high dielectric constant) metal through an electroplating process, this At this time, the source and drain of the entire semiconductor have actually been formed, and then wait for photolithography.

This is a very complicated step in the current CPU manufacturing process. The photoetching process uses light of a certain wavelength to carve corresponding notches in the photosensitive layer, thereby changing the chemical properties of the material there.

This technology has extremely strict requirements on the wavelength of the light used, requiring the use of short-wavelength ultraviolet rays and lenses with large curvatures.The etch process can also be affected by smears on the wafer.

Each step of etching is a complex and delicate process.The amount of data needed to design each step of the process can be measured in units of 10GB, and the etching steps required to manufacture each processor are more than 20 steps, and each step is a layer of etching.

If the etched drawing of each layer is enlarged many times, it can be compared with the map of the entire New York City plus the suburbs, and it is even more complicated. Just imagine reducing the entire map of New York to a chip with an actual area of ​​only 100 square millimeters. On, then this chip.

When these etch jobs are all done, the wafer is flipped over.Short-wavelength light is irradiated onto the photosensitive layer of the wafer through the hollowed-out notch on the quartz template, and then the light and the template are removed.The exposed photosensitive layer material is chemically removed, and silicon dioxide is formed immediately below the void.

Photoresist is applied to the surface of the wafer, and then the designed circuit is "projected" on the surface of the photoresist through a photolithography machine in a manner similar to the exposure of camera film.The exposed photoresist will become soluble. After being washed away with chemicals, the metal layer not protected by the photoresist will also be dissolved, exposing the formed gate, also called the gate level - at this point, a transistor In fact, it is already fully formed.

After that, copper is covered on the surface of the gate, source and drain by electroplating to form three conductive contacts of the transistor, and the copper (wire) interconnection layer between different transistors is further completed - at this time, a CPU The circuit part is manufactured.
