System on Chip (SoC) is a highly integrated semiconductor device that combines multiple electronic system components into a single chip. It typically integrates processors (CPU/GPU/DSP), memory, input/output interfaces, and specialized accelerators. SoCs serve as the core processing units for embedded systems, enabling compact, power-efficient, and cost-effective solutions. Their importance spans modern technology domains including mobile computing, IoT, automotive electronics, and AI edge computing.
