Computing system integrated into a larger system

Template:Infobox computing

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today.

Overview

Embedded systems are designed to perform a specific task, in contrast to general-purpose computers like personal computers or supercomputers. They are typically optimized for efficiency and reliability, often operating in real-time environments.

Components

An embedded system typically includes:

• A microcontroller or microprocessor.
• Memory (both RAM and ROM).
• Input/output interfaces.
• Software that performs the specific task.

Applications

Embedded systems are used in a wide range of applications, including:

• Consumer electronics such as smartphones, televisions, and microwave ovens.
• Automotive systems like ABS and ECUs.
• Medical devices such as pacemakers and MRI machines.
• Industrial automation including robotics and control systems.
• Telecommunications equipment like routers and switches.

Design Considerations

Designing an embedded system involves several considerations:

• **Real-time operation**: Many embedded systems must operate in real-time, meaning they must respond to inputs within a certain time frame.
• **Power consumption**: Especially important in battery-operated devices.
• **Reliability and stability**: Critical in applications like medical devices and automotive systems.
• **Size and weight**: Often need to be minimized, particularly in portable devices.

Development Tools

Development of embedded systems typically involves:

• IDEs for writing and debugging code.
• Compilers and assemblers for converting code into machine language.
• Simulators and emulators for testing the system before deployment.
