What Is an Embedded OS (Operating System)?

Working programs management the {hardware} of a pc. They handle sources, expose the {hardware} to customers for growing functions, and execute code.

However not all working programs are created equal.

The place desktop OSes like Home windows are all over the place, different OSes are hidden from our view. Most individuals don’t even know they exist.

We’re speaking about embedded working programs.

Let’s see what’s an embedded OS, and the way is it completely different from a non-embedded OS?

What Is an Embedded OS?

Operating system representation

An embedded working system is a bit of software program that’s geared toward controlling an embedded system.

An embedded system is a mix of {hardware} and software program used to carry out a extremely specialised activity. For example, contemplate the instance of a contemporary sensible TV. The microprocessor and the related {hardware} contained in the TV are managed by an embedded OS.

So, an embedded OS controls the {hardware} sources of an embedded system and permits code to run on the {hardware}. The code that an embedded OS runs performs fastened duties like controlling Web of Issues (IoT) units.

How Does an Embedded OS Work?

An embedded OS works like a daily OS with some key variations. As a result of an embedded OS is used to handle a system with far fewer sources than a full-fledged desktop OS, it’s extremely environment friendly and solely performs a set set of capabilities.


Let’s take the instance of an embedded OS working inside a doorbell digital camera like Ring. The embedded OS controlling the digital camera {hardware} executes that code that lets the digital camera do its job.

From connecting to the Wi-Fi community to detecting movement and recording video, the embedded OS is accountable for managing {hardware} sources to make all of it attainable.

On the highest stage, each time a tool with an embedded system is powered on, the embedded OS powering the system boots up. Throughout this boot-up part, all of the code that the embedded system requires to perform, together with the OS, can also be loaded and made prepared for execution.

Subsequently, not like a desktop OS, an embedded OS doesn’t must load code from reminiscence each time it must execute a perform.

Varieties of Embedded OS

Embedded OSes are tailor-made to satisfy the wants of the programs that they are going to be utilized in. The place some embedded OSes management programs that carry out just one activity on repeat, different embedded OSes handle programs that carry out a number of duties at a time.

Typically, embedded working programs are divided into multitasking, real-time, and single loop.


A multitasking embedded OS is an OS that controls an embedded system that should carry out a number of duties. The duties could also be carried out concurrently if the microprocessor used within the embedded system is able to it, or they could be scheduled to run in response to the scheduling algorithm.

An instance of a multitasking embedded OS is the working system utilized in Web of Issues units like sensible audio system. The sensible audio system must not solely output music but in addition hook up with the web and seek for music.


An actual-time embedded OS is one which works below strict time constraints. Such an embedded OS should obtain and course of inputs within the allotted time or the system fails.

Think about the instance of an emergency braking system in vehicles. As quickly because the system detects {that a} collision is imminent, the embedded OS prompts the braking system. If the OS fails to provoke the brakes in time, a collision can occur with critical penalties.

Single Loop

A single loop embedded OS is a kind of OS that performs a single perform repeatedly. The one job of such an embedded OS is to take the enter and produce an output, on a loop.

A typical instance of a single loop embedded OS is the OS utilized in motion-sensing lights. Movement sensing lights sense movement and the embedded system turns the lights on if movement is detected.

Embedded vs. Non-Embedded OS: What is the Distinction?

The largest distinction between an embedded OS and a non-embedded OS is the appliance set the working system runs. Within the case of an embedded OS, the appliance set is fastened. The {hardware} of the embedded system is designed to run that particular utility set.

However, non-embedded OSes like Home windows and macOS are designed to provide {hardware} entry to person functions. Customers can set up any app they need so long as it’s designed to run on the OS. The {hardware} {that a} non-embedded OS runs on can also be customizable to some extent.

Furthermore, an embedded OS is specialised. In different phrases, completely different embedded programs have completely different embedded OSes. Non-embedded OSes, however, are general-purpose and help quite a lot of {hardware} configurations.

Usually, a system that an embedded OS controls is commonly a part of a much bigger system. For example, an embedded system used to measure the temperature of a room works as a part of a much bigger local weather management system or the top product.

Non-embedded working programs management the top product itself.

Widespread Makes use of of an Embedded OS

Embedded working programs are all over the place round us. Some frequent examples of embedded OSes are those utilized in:

  • Web of Issues units like sensible mild bulbs and sensible temperature sensors and many others.
  • Vehicles for local weather management and upkeep.
  • Airplane navigation programs.
  • GPS trackers and health trackers.

These are only a few examples of embedded OSes. Typically, each microcontroller has an embedded OS operating issues behind the scenes.

Embedded OSes Are Essential for Applied sciences Round Us to Work

Most of us don’t notice the affect that embedded OSes have on our lives. From built-in smoke and temperature sensors inside our houses to the operation of medical tools, embedded working programs are essential for the applied sciences round us to work.

So, in order for you a deeper appreciation of embedded OSes, spend money on a wise residence gadget. For example, a wise lock is an superior, easy option to begin integrating clever, on a regular basis tech into your life.
