A System on a Chip (SoC) is an integrated circuit that combines various components of a computer or electronic system onto a single chip. These components typically include a central processing unit (CPU), memory interfaces, input/output devices, and interfaces, along with peripherals like GPUs, Wi-Fi, cellular network modems, and more. SoCs can also incorporate digital, analog, mixed-signal, and radio frequency signal processing functions. They are commonly used in mobile computing devices like smartphones due to their compact design and power efficiency.
These chips are designed to be fully or nearly fully integrated across different component modules, leading to reduced power consumption and smaller semiconductor areas compared to multi-chip architectures. While SoCs offer advantages like lower power consumption and smaller form factors, they come with the trade-off of reduced component replaceability.
The evolution of SoC technology has led to tighter integration of components in the hardware industry, influenced by the mobile and embedded computing markets. SoCs are crucial in modern electronics due to their ability to pack significant processing power and memory into small devices. As technology advances, SoCs are expected to play a key role in future innovations such as nanorobots for medical applications and advanced sensory devices for individuals with disabilities.
