Smartphones and Tablet don’t just use processors, they use what’s called a system on a chip. It is equivalent of a computer motherboard , including main processor, graphics processor and memory on a single chip.
A System on chip consists of many components such as one or more central processors , often using a design from an ARM. Modern SoCs also come with advanced graphics capabilities that can surpass game consoles and Nintendo Wii.
Types of SoC:
- SoCs built around a micro controller.
- SoCs built around a micro processor.
- Specialized SoCs designed for specific applications that do not fit into the above two categories.
