An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system.
At the core is an integrated circuit designed to carry out computation for real-time operations.
Complexities range from a single microcontroller to a suite of processors with connected peripherals and networks; from no user interface to complex graphical user interfaces. The complexity of an embedded system varies significantly depending on the task for which it is designed.
Embedded system applications range from digital watches and microwaves to hybrid vehicles and avionics. As much as 98% of all microprocessors now manufactured are used in embedded systems.
Consequently, embedded systems are present everywhere although invisible to the user. Here are some of the applications of the embedded system which use a powerful operating system (OS) like Embedded Linux, Android, and Windows CE:
- Smart homes
- Aerospace and defense
The core of any embedded target is the electronic hardware – which resides on a Printed Circuit Board. The embedded development board is divided into five modules. They are Processor, Memory, Input devices, Output devices, and Bus controllers.
Hardware abstraction layer (HAL) is the fundamental resource of any embedded device and choosing a particular component depends on the requirement and specification of the designer. In the global market, there are many variants of hardware produced for different applications.
