A system-on-chip (SOC) is an integrated circuit that combines all of the functions of a computer on one microchip. Commonly found in smartphones, wireless routers, tablets and wearable tech, system-on-chips process the increasingly complex computing needs of many small devices.
If you own a handheld electronic device, it's most likely powered by a system-on-chip. Their low power consumption makes them suitable for use in small applications. They may combine digital, analogue, mixed-signal and even radio-frequency functions all on one chip.
A system-on-chip can include various elements, depending on how it's used. The general breakdown tends to be:
