A washing machine uses one to control its wash cycles. The operating system in an embedded system, such as Microsoft Windows, is usually made just for its specific function. This helps it work better and use fewer resources.
How Embedded Systems Work?
At their core, embedded systems use microprocessors or microcontrollers. They follow instructions that are coded in their software, which requires little memory. These instructions tell the system how to work with its hardware and the outside world. Programming languages like C, C++, and Assembly help create the software that controls embedded systems.
The user interface can be simple, like buttons and lights, or more complex, like screens with graphics. This depends on what the system is for. For example, in a digital camera, the embedded system handles capturing, processing, and saving images. It also includes a graphical user interface for adjusting settings and viewing images. On the other hand, a traffic light’s embedded system only controls the light changes. It does not have a user interface like a camera. Mobile devices, such as smartphones, show how embedded systems can have detailed user interfaces that manage calls, videos, and different applications.
Types of Embedded Systems
Embedded systems can be sorted by how complex and functional they are. Standalone systems, like digital watches and microwave ovens, as well as video game consoles, work on their own and do not need to connect with other systems. In contrast, networked systems, such as home security systems and internet-connected appliances, rely on network connections to share information and data.
Real-time embedded systems are essential where precise timing and quick responses are needed to provide the required output. This includes devices like medical devices and industrial control systems. They must react to inputs quickly, which helps them work accurately and reliably. The complexity of an embedded system comes from several factors. These include the power of its integrated circuit, the number of peripheral devices it controls, and how complicated its software is.
