This includes the central processing unit (CPU), memory, input/output ports, and secondary storage, among other components. The primary advantage of SoC is its ability to deliver high performance while consuming less power, making it a cornerstone in the development of modern electronic devices.

Components of SoC

1. CPU (Central Processing Unit): The brain of the SoC, responsible for executing instructions and processing data.
2. GPU (Graphics Processing Unit): Handles rendering of images and videos, crucial for multimedia applications.
3. Memory: Includes both volatile (RAM) and non-volatile (ROM) memory, essential for storing data and instructions.
4. I/O Ports: Interfaces for connecting external devices, such as USB, HDMI, and Ethernet ports.
5. Secondary Storage: Embedded storage solutions like flash memory for long-term data retention.
6. Other Components: May include specialized processors like DSPs (Digital Signal Processors), AI accelerators, and more.
