What is Embedded System?

Knowledge about Embedded System

Components of Embedded Systems:

 Microcontroller/Microprocessor:
The core processing unit responsible for executing instructions and controlling the overall operation of the embedded system.

Memory: Stores program code and data. It includes both read-only memory (ROM) for storing permanent data and random-access memory (RAM) for temporary data storage.

Input/Output (I/O) Interfaces: Connect the embedded system to external devices, sensors, and actuators. These interfaces enable communication with the system’s surroundings.

Sensors and Actuators: Sensors collect data from the environment, while actuators perform actions based on the system’s computations. They are crucial for embedded systems in applications such as robotics and automation.

Communication Interfaces: Enable communication between the embedded system and external devices or networks. This can include interfaces such as UART, SPI, I2C, Ethernet, or wireless communication protocols.

Real-Time Clock (RTC): Keeps track of time and is essential for applications that require time-sensitive operations.

Power Supply: Provides the necessary power for the embedded system to operate. In battery-powered devices, power management is a critical consideration.

Operating System (OS) or Real-Time Operating System (RTOS): Some embedded systems use a lightweight operating system or real-time operating system to manage tasks, scheduling, and resource allocation.
