Medical equipment – Most modern medical equipment is equipped with embedded devices. It should be free of any health hazard and provide a very friendly GUI. So, generally, these types of equipment use sophisticated software and RTOS. As I told in the previous section, an embedded system is not a general-purpose system, instead, it’s designed to perform specific functions.

In an embedded system, different types of operating systems exist. Some of them are RTOS (Real-time operating systems), VxWorks, RTLinux, Nucleus, µCos, mobile embedded, stand-alone, and network embedded systems. An integrated circuit is a miniaturized electronic circuit that’s been combined into a single chip. An IC is basically a single chip that performs one or more dedicated functions within a device. It can be used for a wide range of applications such as in computers and mobile phones, appliances, industrial equipment, cars, and medical devices. Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase its reliability and performance.

User-mode processes implement major functions such as file systems, network interfaces, etc. Some embedded systems are predominantly controlled by interrupts. For high-volume systems such as mobile phones, minimizing cost is usually the primary design consideration.

Such an embedded OS must receive and process inputs in the allotted time or the system fails. Let’s take the example of an embedded OS working inside a doorbell camera like Ring. The embedded OS controlling the camera hardware executes that code that lets the camera do its job. An embedded OS works like a regular OS with some key differences. Because an embedded OS is used to manage a system with far fewer resources than a full-fledged desktop OS, it is highly efficient and only performs a fixed set of functions.

Military applications – surveillance systems, cybersecurity systems, Defense and aerospace, Communication, etc. Telecommunications – telephone switches, mobile phones, broadband networks, robotics in the transmission line, etc. The applications installed in the computer system can be altered by the end user. Depending on the user requirement, any type of general applications can be installed and can be deleted by the user. We hope you must be wondering about this topic of an embedded system. It’s quite theoretical, but when you actually start getting things, you will be more clear on the magic of this.

How would you structure your code if you were creating it for a real-time operating system? What kind of restrictions on the system are you looking to impose? Think about the kinds of situations that might lead to unexpectedly long response times in the future. In certain cases, memory access may be slowed down in some way.

In other words, an embedded system is a computer that’s been built into another device to control or monitor a task or process. In Small-scaled embedded systems frequently use an 8-bit microcontroller. Embedded systems that operate independently of a host system are known as standalone embedded systems. They execute a specific purpose, much like any other embedded system. Small systems that are engineered to be small and light are known as mobile embedded systems.


In an automobile, an embedded system is used for monitoring, controlling, and managing the automobile’s engine and other systems. This produces the desired result in a predetermined amount of time.
