- The baseband processor is an important part of a mobile phone. It is equivalent to a protocol processor and is responsible for data processing and storage. The main components are digital signal processor (DSP), microcontroller (MCU), memory (SRAM, Flash) and other units. .
- The main function is to support several communication standards, provide multimedia functions and interfaces for multimedia displays, image sensors and audio equipment.

- The basic function of the MCU in the traditional baseband processor is to complete the following two functions: one is the control code that runs the physical layer of the communication protocol; the other is the upper-layer software that controls the communication protocol, including the presentation layer or human-machine interface (MMI). The basic function of DSP is to complete a large number of scientific calculation functions at the physical layer, including channel equalization, channel encoding and decoding, and telephone speech encoding and decoding.
- As multimedia functions increase, one of the ways to increase the capabilities of mobile phones is to increase the integration of the baseband processor. Currently, the baseband processor is a highly complex system-on-chip (SoC), which not only supports several communication standards, but also provides multimedia functions and interfaces for multimedia displays, image sensors, and audio devices.
