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.<br />
<br />
== Overview ==<br />
Embedded systems are designed to perform a specific task, in contrast to general-purpose computers that are designed to handle a wide range of tasks. They are typically optimized for efficiency and reliability, often operating in real-time environments. <br />
<br />
== Components ==<br />
An embedded system typically includes:<br />
* A [[microcontroller]] or [[microprocessor]].<br />
* [[Memory]] (RAM, ROM, EEPROM, etc.).<br />
* [[Input/output]] interfaces.<br />
* [[Software]] (firmware) that is specifically designed for the task.<br />
<br />
== Applications ==<br />
Embedded systems are used in a wide range of applications, including:<br />
* [[Consumer electronics]] (e.g., [[smartphones]], [[televisions]], [[digital cameras]]).<br />
* [[Automotive]] systems (e.g., [[engine control units]], [[airbag]] systems, [[infotainment]] systems).<br />
* [[Industrial automation]] (e.g., [[programmable logic controller]]s, [[robotics]]).<br />
* [[Medical devices]] (e.g., [[pacemaker]]s, [[medical imaging]] systems).<br />
* [[Telecommunications]] (e.g., [[routers]], [[switches]], [[modems]]).<br />
<br />
== Design Considerations ==<br />
Designing an embedded system involves several considerations:<br />
* **Real-time operation**: Many embedded systems must operate in real-time, meaning they must respond to inputs within a certain time frame.<br />
* **Power consumption**: Especially important for battery-powered devices.<br />
* **Reliability and stability**: Embedded systems often operate in critical environments where failure is not an option.<br />
* **Size and weight**: Many embedded systems need to be compact and lightweight.<br />
<br />
== Development Tools ==<br />
Development of embedded systems typically involves:<br />
* [[Integrated development environment]]s (IDEs).<br />
* [[Compilers]] and [[debuggers]].<br />
* [[Emulators]] and [[simulators]].<br />
* [[In-circuit emulator]]s (ICEs).<br />
<br />
