What is Embedded System? Types, Examples, Applications
Embedded system is also known as “Embedded Computer“. Embedded system is a combination of computer hardware circuitry and software programs, and then it delivers the perfect solution of any specific problem, then it is called the “Embedded System“. It is capable to perform specific task independently, or it can be used in any vast system. Due to this advantage of embedded system, it is used in various applications.

Embedded system is made with electronics parts, and on this electronic system, to install the predefined softwares then it has to capable to perform single or multiple tasks according to the application.
Embedded Operating System refers as a combination of software and hardware. Embedded Operating system is written with programming code, and it helps to convert hardware language into software language like as C, C++, and finally it produces the result that easily can be understandable by human being in the different formats like as pictures, text, and voice.
The Evolution of Embedded Systems
Embedded systems design is changing and following enterprise systems by becoming more flexible and software-defined. Traditionally, embedded systems were purpose-built using closed architectures that were unique to each device. They run a real-time operating system (RTOS) like VxWorks in systems that have fixed time constraints, where predictability is key. The RTOS ensures that these systems do not fail. Alternatively, systems without real-time requirements can run customized versions of Linux, such as Wind River Linux.
Why Embedded Systems Design Is Changing
Drivers of changes in embedded systems design include improvements in hardware as well as the continuing evolution in software development methods.
At the hardware level, it’s now possible to do more with a single CPU. Rather than host just one application, new multi-core systems on a chip (SoCs) can support multiple applications on a single hardware platform while still maintaining modest power and cost requirements. At the same time, advances in software development techniques point toward systems that are more software-defined and fluid than their predecessors.
Core Values Remain
While there are many changes in the embedded systems world, the core requirements have remained the same. Embedded systems have to be secure, safe, reliable, and certifiable.
- Security: Cyberattacks have become more common at the same time that completely isolated systems are becoming rarer. Embedded systems engineers are taking security even more seriously than before.
- Safety: This refers to the system’s ability to make sure that it does not have an adverse effect on its environment, whatever that might be. Sectors such as industrial, transportation, aerospace, and automotive can cause deaths or environmental disasters if their embedded systems malfunction. In this regard, determinism, meaning the predictability and reliability of performance, is of paramount importance. A failure in one zone should not trigger a failure of the entire system.
- Reliability: Reliability in an embedded systems design means that it will always perform as expected. It should produce the same outcome, in the same time frame, the first or millionth time it is activated. After all, too late is not an option in systems that cannot fail.
- Certifiable: The certification process is a critical and costly part of development for many embedded systems. Certification in legacy systems must be maintained and leveraged, while ease of certification for future systems must be managed.
