An Embedded System is a system that has software embedded into computer-hardware, which makes a system dedicated for a variety of application or specific part of an application or product or part of a larger system.

An embedded system can be a small independent system or a large combinational system. It is a microcontroller-based control system used to perform a specific task of operation.


Types of embedded systems


When considering performance and functional requirements, embedded systems are categorized into real-time embedded systemsstandalone embedded systemsnetworked embedded systems, and mobile embedded systems.


  • Real-time embedded systems prioritize prompt output generation and can be classified as soft real-time (lenient deadlines) or hard real-time (strict deadlines).


  • Standalone embedded systems can function independently without a host computer.


  • Networked embedded systems rely on network connections and communication for output generation.


  • Mobile embedded systems refer to small, portable devices such as smartphones and laptops.



Basic Structure of an Embedded System


Let's see the block diagram shows the basic structure of an embedded system.

Characteristics of Embedded System


Let's see the general characteristics of embedded system in the real-time computation of system:


  1. An embedded system is software embedded into computer hardware that makes a system dedicated to be used for variety of application.
  2. Embedded system generally used for do specific task that provide real-time output on the basis of various characteristics of an embedded system.
  3. Embedded system may contain a smaller part within a larger device that used for serving the more specific application to perform variety of task using hardware-software intermixing configuration.
  4. It provides high reliability and real-time computation ability.
