An embedded system is a computer system that has a dedicated function within a larger mechanical or electronic system. It is typically embedded as part of a complete device, often including electrical or electronic hardware and mechanical parts. Embedded systems are designed to perform a specific task and are often used in devices that require real-time computing constraints. They are low-cost, low-power-consuming, small computers that are embedded in other mechanical or electrical systems.
Embedded systems have three primary components: hardware, application software, and real-time operating system (RTOS) . The hardware of embedded systems typically includes microprocessors and microcontrollers, which are connected to other basic computing devices such as memory chips, power supplies, and LCD displays. The application software of embedded systems is typically made up of specialized programming tools that are designed to perform a specific task. The RTOS is responsible for managing the systems resources and ensuring that the system operates in real-time.
Embedded systems are used in a wide range of technologies across an array of industries. Some examples include home security systems, point of sale (POS) systems, fire alarms, microwave ovens, and engine control systems of modern automobiles.
