Detailed explanation of chip classification basic knowledge-type and standard understanding

The chip is also called microcirculation, micro -chip, and integrated circuit. It is actually a collective name for semiconductor component products.chipThere are many classifications. According to different processing signals, it can be divided into two types: analog chip and digital chip.In simple terms, the simulation chip uses the amplification effect of the transistor, and the digital simulation chip uses the switching of the crystal.

Specifically, the analog chip is used to generate, enlarge and process various simulation signals, with a variety of fine types, including the mold conversion chip (ADC), amplifier chip, power management chip, PLL, and so on.The difficulty of simulated chip design is that there are too many non -ideal effects. It requires solid basic knowledge and rich experience, such as small signal analysis, time domain frequency domain analysis, and so on.

In contrast, digital chips are used to generate, enlarge and process various digital signals. Digital chips generally perform logical operations. The CPU, memory chip and DSP chip are all digital chips.The difficulty of digital chip design is that the chip size is large and the process requirements are complicated, so multi -teams are usually jointly developed.

The CPU is a central processor. It is the core of the computing and control of the computer system. It is the final execution unit for information processing and program operation.The CPU is the core hardware unit of all hardware resources (such as memory, input and output units) of the computer (such as memory, input and output units).
The main types and standards of chip classification basic knowledge

According to international standard classification methods, it can be divided into: integrated circuits, separate devices, sensors, optoelectronics;

According to the circuit, it can be divided into: analog integrated circuit, digital integration circuit, and hybrid signal integration circuit;

Classification according to different processing signals can be divided into: analog chip: chip that processs analog signals is called analog chip; digital chip: chip that processs digital signals is called digital chip.So what is an analog signal and digital signal?Sims signal: Simple point is continuous signals, that is, continuously issued; digital signals: discrete signals, simple points are discontinuous.

Classified according to the function of use can be divided into: GPU, CPU, FPGA, DSP, ASIC, SOC;

Classified according to different application scenarios: civilian grade (consumer level), industrial grade, automobile grade, aerospace level;

Because there are millions or billions of components on a single chip, each component cannot be located alone.The chip is too small and cannot be welded and connected.Instead, the designer uses a special programming language to create a small circuit element and combine them to gradually increase the size and density of the component on the chip to meet the application needs.
