Related to System-on-chip: SOCS
SoC(1) (Service Organization Control) An audit of a service organization. A SOC Type I report covers a point of time; for example, June 30, whereas Type II covers a period such as one year.
(2) (Security Operations Center) A facility SOC monitors human and vehicle access to the premises. An IT SOC monitors hardware, software and networks. See NOC.
(3) (System-On-Chip) Pronounced "S-O-C." An electronic system on a single chip. Although not called a system-on-chip (SoC), the first chip of this kind was the microcontroller (MCU), which contains the CPU along with RAM, storage and I/O. SoCs typically include a number of CPU cores along with graphics (GPU) and other processing components, and they are used in many computing platforms, including smartphones, tablets, robots, video game consoles and industrial machinery. See microcontroller.
The more functions contained within a single chip, the fewer electronic circuits are required to interface between multiple chips. In addition, systems can be miniaturized for handheld use with an ancillary reduction in power. See PSoC, Versal, mobile platform, system in package and package on package.
|A smartphone SoC has CPU cores and a built-in graphics processor (GPU) at the very least; however, it can also contain additional processing units (see below). Each block in this diagram represents a separate chip; however, a phone also has chips for power management and charging. There are additional chips for auxiliary functions. See GPU.|

|Used in Android phones, Qualcomm's mobile SoCs are very comprehensive. This single chip contains all the major processing components required in a modern smartphone. The Snapdragon 855 debuted in 2019. See ISP, GPU and neural processing unit.|
