What is Embedded System Design?

Embedded system design refers to the process of creating dedicated computing systems that are integrated into larger devices or machines. These systems perform specific tasks, often in real-time, and include hardware and software components tailored for optimal functionality.

Key Components of Embedded System Design

1. Microcontrollers (MCUs) and Microprocessors (MPUs): The brains of the system, responsible for processing data and executing instructions.
2. Sensors and Actuators: Enable interaction with the physical environment by collecting data and performing actions.
3. Memory and Storage: Store program code, operational data, and system configurations.
4. Power Management: Ensures energy efficiency and uninterrupted operation.
5. Communication Interfaces: Facilitate data exchange between components and external systems, such as UART, SPI, I2C, and wireless protocols.
6. Software and Firmware: Includes real-time operating systems (RTOS), application code, and drivers that define system functionality.
