How does the CPU of a mobile system work?

A mobile system has to cater to a variety of operations and applications and its CPU has to manage all these. Thus the CPU of a mobile system has many sub-processors that help it control and manage diverse applications. The CPU of a mobile manages all these types of applications and operations:

1. Manages communications while connecting to radio transceivers and SIM.
2. Manages audio through ADC (analog to digital converter) and DAC (digital to analog converter).
3. Manages display and touch sensitive sensors and interface.
4. Works in tandem with memory and storage.
