Chip classification
Is there a systematic classification method for so many chips? There are actually many ways to classify chips:
According to the signal processing method, it can be divided into analog chips and digital chips
Signals are divided into analog signals and digital signals, and digital chips are used to process digital signals, such as CPUs, logic circuits, etc; Analog chips are used to process analog signals, such as operational amplifiers, linear regulators, reference voltage sources, etc.
Nowadays, most chips have both digital and analog capabilities, and there is no absolute standard for which type of product a chip belongs to. It is usually distinguished based on the core functions of the chip.
According to application scenarios, it can be divided into aerospace grade chips, automotive grade chips, industrial grade chips, and commercial grade chips
Chips can be used in various fields such as aerospace, automotive, industrial, and consumer industries, and are so divided because these fields have different performance requirements for chips, such as temperature range, accuracy, and continuous trouble-free operation time (lifespan). For example:
Industrial grade chips have a wider temperature range than commercial grade chips, while aerospace grade chips have the best performance and are also the most expensive.
According to usage functions, it can be divided into GPU, CPU, FPGA, DSP, ASIC, SoC
Just mentioned touch chips, storage chips, Bluetooth chips It is classified based on its usage function. There is also a common saying among companies that 'our main business is CPU chips/WIFI chips', which is also divided from a functional perspective.
