A System on a Chip (SoC) integrates all components of a computer or electronic system into a single chip. This compact design combines a central processing unit (CPU), memory, input/output ports, and other peripherals. SoCs are the backbone of modern compact and portable devices, driving innovations in smartphones, IoT devices, and wearable technology.
Key Components of SoC
1. Central Processing Unit (CPU):
Acts as the brain of the system, performing general-purpose computations. CPUs in SoCs are often customized for specific tasks.
2. Graphics Processing Unit (GPU):
Handles image rendering and graphics-intensive tasks, crucial for gaming and multimedia applications.
3. Memory:
RAM: Provides temporary storage for active processes.
ROM/Flash Memory: Stores firmware and essential software.
4. Peripherals and Interfaces:
Includes USB controllers, audio codecs, and networking components like Wi-Fi and Bluetooth.
5. Power Management Unit (PMU):
Ensures efficient energy usage, crucial for battery-powered devices.
6. Application-Specific Modules:
Custom-designed features such as AI accelerators, machine learning cores, or digital signal processors (DSPs).
Characteristics of SoCs
Integration: Combines multiple components into a single chip, reducing size and complexity.
Energy Efficiency: Optimized for low power consumption, extending battery life.
Cost-Effective: Reduces manufacturing costs by eliminating the need for multiple chips.
Compact Design: Ideal for small devices and space-constrained applications.
Applications of SoC

Code Example: Basic SoC Peripheral Control
#include <stdio.h>
// Simulating an LED toggle on SoC GPIO pin
void toggleLED(int pin) {
printf(“Toggling LED on GPIO pin %d\n”, pin);
}
int main() {
int gpioPin = 5; // Example GPIO pin
toggleLED(gpioPin);
return 0;
}
