By the early 1980s, memory, input and output system components had been integrated into the same chip as the processor forming a microcontroller. Microcontrollers find applications https://www.globalcloudteam.com/ where a general-purpose computer would be too costly. As the cost of microprocessors and microcontrollers fell, the prevalence of embedded systems increased.
Industrial machines often have embedded automation systems that perform specific monitoring and control functions. Because of these complexities, it is common for organizations to use an off-the-shelf RTOS, allowing the application programmers to concentrate on device functionality rather than operating system services. The choice to include an RTOS brings in its own issues, however, as the selection must be made prior to starting the application development process. This timing forces developers to choose the embedded operating system for their device based on current requirements and so restricts future options to a large extent. PC/104 and PC/104+ are examples of standards for ready-made computer boards intended for small, low-volume embedded and ruggedized systems. These are mostly x86-based and often physically small compared to a standard PC, although still quite large compared to most simple (8/16-bit) embedded systems.
Applications of Embedded Systems
If you want to pursue a career in embedded systems development, you can become an embedded systems engineer. Engineering careers belong to the occupational field of architecture and engineering. The US Bureau of Labor Statistics projects a 4 percent job growth in this category between 2021 and 2031. This figure translates into approximately 91,300 new jobs and is in line with the average growth for all occupations .
Often, embedded systems are used in real-time operating environments and use a real-time operating system to communicate with the hardware. In these instances, stripped-down versions of the Linux operating system are commonly deployed, although other OSes have been pared down to run on embedded systems, including Embedded Java and Windows IoT . MarketsandMarkets, a business-to-business research firm, predicted that the embedded market will be worth $116.2 billion by 2025. Chip manufacturers for embedded systems include many well-known technology companies, such as Apple, IBM, Intel and Texas Instruments. The expected growth is partially due to the continued investmentin artificial intelligence , mobile computing and the need for chips designed for high-level processing. Healthcare facilities use real-time embedded systems in medical devices to monitor the patients’ health, communicate with other devices and humans, store the information of the patient, etc.
How to become an embedded systems engineer
Each microcontroller (Arduino, PIC Microcontroller, 8051 Microcontroller etc.) performs its own dedicated task. Today cars use embedded systems to replace old traditional systems. Nowadays, modern cars have a variety of embedded systems that perform a variety of activities based on their uses in the vehicle. Basic station equipment that includes a ticket vending machine, automatic gate machine, and ticket checking machine is known as an AFC. These are embedded systems that allow for speedier transactions, smoother operations, and more efficient money collecting. Embedded system software is written in a high-level language and then compiled to perform a specified task in the hardware’s non-volatile memory.
Fitness trackers are wearable devices that can monitor your health and track activities like sleeping, running, and walking. These devices use embedded systems to garner data related to your heart rate, body temperature, and the number of footsteps, which is further sent to servers via WAN like LTE or GPRS. Simple control loops call subroutines, which manage a specific part of the hardware or embedded programming. However, they do not necessarily belong to a host system, unlike other embedded systems. Mobile embedded systems are small-sized systems that are designed to be portable. The sensor reads external inputs, the converters make that input readable to the processor, and the processor turns that information into useful output for the embedded system.

The thermostat controls, which are achieved by an embedded system, are critical for these systems to change the temperature. When the system runs indefinitely, the power dissipation for activities like run, halt, and wake up must be limited. Get the latest software testing news and resources delivered to your inbox.
Embedded systems are far more ubiquitous than the general-purpose computer found in almost every home. As such, there are many examples of embedded systems in daily life. Manufacturers of these devices must follow the standards and prove via audits that they perform their due diligence and have addressed all concerns for security and safety. This type embedded system definition of hardware and software development is time-consuming and expensive to build and test, but essential to assure correct behavior when deployed. Medium-scale embedded systems use a larger microcontroller (16-32 bit) and often link microcontrollers together. They can contain embedded systems, like sensors, and can be embedded systems themselves.
Processors in embedded systems
Consumer electronics include MP3 players, television sets, mobile phones, video game consoles, digital cameras, GPS receivers, and printers. Household appliances, such as microwave ovens, washing machines and dishwashers, include embedded systems to provide flexibility, efficiency and features. Advanced heating, ventilation, and air conditioning systems use networked thermostats to more accurately and efficiently control temperature that can change by time of day and season. Home automation uses wired- and wireless-networking that can be used to control lights, climate, security, audio/visual, surveillance, etc., all of which use embedded devices for sensing and controlling.
These Embedded Systems Examples belong to real-life appliances and devices, which we use in our daily routine. I hope you already have the idea of embedded systems but if you don’t then you can find the introduction to embedded systems in my previous article What is Embedded System? I have also shared few Embedded Systems Examples in this article.
Sequential access vs direct access vs random access in operating system
Closing and opening of valves for adding water is checked through level sensors by microcontroller like PIC Microcontroller. Almost every industry and office has security systems that can recognize the workers from their faces or identity cards. Today images are stored and processed in form of digital data in bits. A digital camera has basically three functions, to capture an image which we call data, to store image data, and to represent this data. Embedded systems have been used in medical equipment at healthcare institutions for a long time. Embedded systems are being used in a new class of medical gadgets to assist treat patients who require ongoing monitoring and treatment at home.
- For example, the Gibson Robot Guitar features an embedded system for tuning the strings, but the overall purpose of the Robot Guitar is to play music.
- They are low-cost, low-power-consuming, small computers that are embedded in other mechanical or electrical systems.
- Automated software testing solutions that help with a wide range of needs and compliance requirements.
- The microcontroller can be written in any programming language like C language, assembly language or any complex language.
Robots use actuators, sensors, and software to detect the surroundings and safely produce the desired output in normal mechanical work. The GPS is a navigation system that synchronizes data about location, time, and velocity using satellites and receivers. To make the use of a global positioning system easier, the receiver or device that receives the data has an integrated embedded system. People can simply find their present location and destination thanks to the incorporated GPS gadgets.

We use both hardware and software components to design final systems or hardware products. Embedded systems always function as part of a complete device — that’s what’s meant by the term embedded. They are low-cost, low-power-consuming, small computers that are embedded in other mechanical or electrical systems. Generally, they comprise a processor, power supply, and memory and communication ports.
