enter) A facility SOC monitors human and vehicle access. An information technology SOC monitors the hardware, software and networks.
hip) Pronounced "S-O-C." An electronic system on a single chip. A system-on-chip (SoC) typically includes a CPU along with graphics and other processing components. For example, a smartphone SoC would include the processor cores, graphics processing unit (GPU), memory caches and a neural processing unit (NPU). In this case, NAND flash storage, RAM, camera, audio, power and numerous small ICs are on the device's motherboard outside the SoC. See GPU
and neural processing unit
The more functions contained within a single chip, the more systems can be miniaturized for handheld use with an ancillary reduction in power. See PSoC

A phone SoC can have as many as eight CPUs and many more components, including memory caches that are staging areas between the RAM and CPU. The SoC may also include image and neural processing engines, which speed up rendering and AI operations respectively. While each block indicates a major chip, the phone also has chips for the camera, battery, power management and external charging port. There are dozens more for auxiliary functions.
