An embedded system is a computer system designed to perform specific tasks and functions within a larger mechanical or electrical system. These systems are designed to be compact, efficient, and reliable, and are typically used in products such as consumer electronics, automotive systems, medical equipment, and industrial automation equipment.
Embedded systems are often built around microprocessors or microcontrollers, which are specialized integrated circuits that combine processing power, memory, and input/output interfaces on a single chip. They may also incorporate other hardware components such as sensors, actuators, and communication interfaces to interact with the physical world.
The software running on embedded systems is usually highly optimized for performance and reliability, and may be written in assembly language, C, or other programming languages. Embedded systems may also use specialized real-time operating systems (RTOS) to manage the system resources and provide predictable response times for critical tasks.
Due to their specialized nature, embedded systems require specific design considerations and development methodologies to ensure they meet the performance, reliability, and safety requirements of the application they are used in.
