If the chip is divided according to the signal processing method, it can be divided into analog chips and digital chips; according to the design concept, it can be divided into general-purpose chips and special-purpose chips; according to the application field, it can be divided into aerospace-grade chips, automotive-grade chips, and industrial-grade chips. And commercial-grade chips; according to the chip manufacturing process, it can be divided into seven-nanometer chips, 14-nanometer chips and 28-nanometer chips. Classifying chips from the perspective of application functions can be divided into processor chips, memory chips, sensors, power chips, communication chips, interface chips, etc. The processor chip is equivalent to the human brain, which is used for thinking, analysis and calculation. Among them, the processor chip is subdivided into the central processing unit graphics processor, the digital signal processor and the microcontroller.

  Memory chips are equivalent to the human cerebral cortex and are used to store information and data. There are also different types of memory chips, which serve different functions.

  The sensor chip is equivalent to the five sense organs of human beings, which can perceive and measure the sound, image, temperature, humidity, pressure and light signal in life, etc.
