Embedded systems are everywhere in our daily lives, from digital watches and smartphones to home appliances and medical devices. But do you understand clearly about: “What is an embedded system?” In this article, Nexle Corporation will explain the easy-to-understand definition, types, use cases, and future! Scroll down to dive into the topic!

What is an Embedded System?

An embedded system is a computer hardware system that utilizes a microprocessor and is equipped with software specifically intended to carry out a specialized purpose. This system may operate independently or as an integral component inside a larger system. An integrated circuit optimized for real-time processing serves as the system’s brain.

There are many levels of complexity, from a single microcontroller to a group of connected processors with peripherals and networks and from no user interface to intricate graphical user interfaces. Depending on the goal for which it was created, an embedded system’s level of complexity might vary significantly.

Up to 98 percent of all manufactured microprocessors are used in embedded systems. Applications for embedded systems include hybrid cars, avionics, digital watches, microwaves, and more.

Use Cases of Embedded Systems

Embedded systems may be found everywhere and in every industry. Whether in simple or complicated work, we could use them without realizing it. Examples of where embedded systems may be used are:

How do Embedded Systems Work?

Embedded systems are designed to work only as part of a bigger device. A low-power embedded computer is a small device that may be found in other mechanical or electrical systems. They typically have a CPU, a power supply, memory, and data and voice transmission connectors. With the help of a communication protocol, embedded systems’ processors may send and receive data with external devices, most often with other embedded systems. The CPU uses the minimal software stored in memory to make sense of this information. In most cases, the software running on an embedded system is written with a particular goal in mind.

A microprocessor or microcontroller might serve as the processor. Simply said, microcontrollers are microprocessors with integrated memory and peripheral interfaces. Microprocessors rely on external integrated circuits instead of incorporating memory and peripherals on the chip. Although both are useful, microprocessors often need supplementary circuitry in addition to microcontrollers due to the microprocessor’s lower level of integration. The acronym “SoC” (system-on-a-chip) is often used to describe these integrated circuits. SoCs are integrated circuits that have different interfaces and processors. They find widespread use in mass-produced embedded systems. Types of SoCs include ASICs and FPGAs, which are specialized chips used in certain applications.

Embedded systems often interact with hardware using a real-time operating system (RTOS) in real-time operating environments. At higher levels of chip capability, when systems are normally fast enough and jobs are tolerant of modest changes in response time, near-real-time techniques are acceptable. Embedded Java and Windows IoT (previously Windows Embedded) are two additional operating systems that have been slimmed down to operate on embedded devices, although Linux is the most popular choice.

Future Trends in Embedded Systems

Developments in fields like AI, augmented and virtual reality, machine learning, deep learning, and the Internet of Things are expected to drive the explosive growth of the embedded systems industry. The cognitive embedded system will benefit from energy efficiency, embedded device security, cloud and mesh networking, deep learning applications, and real-time data visualization tools.

QYResearch estimates that the embedded systems market will grow from its 2017 $69.1 billion to $105.7 billion by the end of 2025.

Embedded systems are essential for many applications we use and depend on. They have three main components: hardware, software, and communication. They are constantly evolving and improving as new technologies and challenges emerge. Nexle Corporation hopes you know more deeply about “What is an embedded system”.
