An embedded system is a controller with a function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts.
What is an embedded system?
Embedded systems are a cornerstone of the electronics industry today. An embedded system is designed for a specific purpose. The system gains its name from the fact that the software is embedded into it for a particular application.
In the Electronics world, an Embedded system is a combination of “hardware and software” i.e. an electronic system that has computer software that is embedded in computer hardware. A hardware platform is generally a microcontroller or processor in which the program is dumped. The hardware has its own software. They are either Machine code (hex code) or Programming code (C, C++ code). For example, take the 8051 controllers. Here we embed the program into it and it performs the task as per the program instructions.
Embedded systems find numerous applications in various fields such as digital electronics, telecommunications, computing network, smart cards, satellite systems, military defence system equipment, research system equipment, and so on. Let us discuss a few practical applications of embedded systems that are used in designing embedded projects as a part of engineering final year electronics projects
