Depending on the complexity and functional requirements, the system-on-chip can be large or small, such as the smallest and simplest 8-bit microcontroller micro-controller system, and the larger, such as a 32-bit embedded system. Their common points are the CPU and rich peripheral peripherals. The point lies in the different processing capabilities of the system and the application fields. Simple single-chip systems are used in electric vehicles and rice cookers, and complex embedded systems such as ARM cores are mostly used in multimedia processing systems, such as mobile phones and tablets.
