Referred to as ADSP). The application processor CPU may include a call UI (User Interface, user interface, Referred to as UI), it is a call interface, a communication framework, an audio management module, an Audio driver, a Codec driver, and an audio data storage area. The call UI is mainly used for displaying a call interface and a logical processing part related to a call, such as a call. Displaying the display of the interface and some buttons on the interface; the communication framework may be logic for maintaining communication work and a control center; the audio management module may be for managing audio related processing units, such as audio on/ Off, call recording, audio mode management (such as hands-free mode management), etc.; the audio data storage area may be a storage center of audio data, such as call audio, normal audio and other audio data storage center; the Audio driver is mainly used It is responsible for managing the operation of modules such as MIC/Speaker; the Codec driver is mainly responsible for managing the operation of the driver audio Codec module. The communication module may include a call control module, an Rx decryption module, and a Tx encryption module. The call control module is mainly a module for managing call related in the communication module, such as link, audio data management, etc.; the Tx encryption The module and the Rx decryption module are mainly used for encrypting/decrypting the generated/received call audio data to ensure the security of the audio data transmission. The ADSP audio data signal processor is mainly used for performing digital-to-analog conversion and operation of audio data. The audio Codec may be a hardware device, mainly used for encoding/decoding a sound signal.
