An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. At the core is an integrated circuit designed to carry out computation for real-time operations. Complexities range from a single microcontroller to a suite of processors with connected peripherals and networks; from no user interface to complex graphical user interfaces. The complexity of an embedded system varies significantly depending on the task for which it is designed.
- They are convenient for mass production. This results in low price per piece.
- The embedded systems are very small in size, hence can be carried and loaded anywhere.
- These systems are fast. They also use less power.
- They improve the product quality.
The industry for embedded systems is expected to continue growing rapidly, driven by the continued development of Artificial Intelligence (AI), Virtual Reality (VR) and Augmented Reality (AR), machine learning , deep learning, and the Internet of Things (IoT). The cognitive embedded system will be at the heart of such trends as: reduced energy consumption, improved security for embedded devices, cloud connectivity and mesh networking, deep learning applications, and visualization tools with real time data. According to a 2018 report published by QYResearch, the global market for the embedded systems industry was valued at $68.9 billion in 2017 and is expected to rise to $105.7 billion by the end of 202
Embedded devices are typically powered by software integrated with hardware such as systems on a chip (SoC), field-programmable gate arrays (FPGA), an integrated circuit (IC) designed to be programmed by an embedded developer for a specific function, and other firmware variations. This makes it difficult to separate software and hardware completely. Embedded systems suppliers in this market could include those that only provide software, such as development and testing tools and real-time operating systems (RTOS); and those that also provide FPGA, SoC, and other firmware products. While embedded systems are a very mature technology overall, with the steady advancement of new and more powerful processors, the technology now enables the next-generation of intelligent devices, machines, equipment, and factories. Embedded systems represent key enabling technology for the smart, connected products, machines, and systems that comprise the Industrial Internet of Things (IIoT) and support the overall digital transformation of industry.
