Digital Base band Processor
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.
