System on chip

A system on a chip or system on chip (SoC or SOC ) is an integrated circuit (also known as an "IC" or "chip") that integrates all components of a computer or other electronic systems.Systems on Chip are in contrast to the common traditional motherboard -based PC architecture, which separates components based on function and connects them through a central interfacing circuit board, so-termed a "mother board".

System on a chip (SoCs) integrate all of these components into a single integrated circuit, as if all these functions were built into the motherboard.A SoC integrates a microcontroller (or
microprocessor ) with advanced peripherals like
graphics processing unit (GPU), Wi-Fi module, or
coprocessor .

Components of System on a Chip (SOC)

. Processor
. Graphics
. Audio
. Bus
. Memory etc.
Finally, SoCs come with a myriad of smaller co-processors that usually don’t get any of the glory. They are nonetheless critical to overall system performance. The video encoding and decoding hardware powers the “camcorder” functionality of smartphones. The image processor ensures that photos are processed properly and saved quickly and the audio processor frees the CPU(s) from having to work on audio signals. Together, all those components -and their associated drivers/software- define the overall performance of a system.
