What are embedded systems?

The five properties of an embedded system

Embedded systems generally have five main features. We briefly explain these. 

• Heterogeneity. Cooperation between different disciplines allows embedded systems to communicate with different types of networks and other embedded systems.
• Invisible. Embedded systems are built into machines or equipment, and users are usually unaware of their existence. This is possible because embedded systems are treated differently from "regular" computers: instead of receiving commands from humans via keyboards or switches, embedded systems automatically respond to their environment without human intervention. This is achieved through sensors, which can analyze voice, temperature or air quality, for example, and respond accordingly.
• Economical in energy consumption. For example, to operate as economically as possible, embedded systems can draw energy from the environment; energy such as sunlight or body heat can be used to power the embedded systems. Economy is very important because most embedded systems are not connected to the grid.
• Flexibility. Flexibility is important to adapt embedded systems to the individual needs of users or neighboring embedded systems. This is where heterogeneity comes in: after all, embedded systems must be able to communicate with neighboring systems. Therefore, the system can configure itself.
• Reliability. Embedded systems must operate independently and reliably over a long period of time. Consider, for example, a car's ABS function, which cannot fail even in the most critical situations.
  

Examples of embedded systems

Chips are becoming cheaper and more flexible. This applies to both chips for processors and chips for sensors and actuators, among other things. Because of this development, embedded systems are increasingly used to make devices smarter. Think for example of home automation, such as window blinds, lighting, mowers and home irrigation systems. But also robots, smartphones, washing machines or cars. The latter category nowadays have dozens of embedded systems for controlling all kinds of things such as safety systems and autonomous driving. Many more devices or goods have embedded systems, without the consumer always being aware of it.
