Embedded software is understood to mean applications that are programmed as part of “embedded software engineering” for special hardware. Often these are machines or devices in the Internet of Things that, in their original function, are not considered to be computers: pacemakers, telephones, television systems, household appliances, medical and aviation technology or, increasingly, automobiles.
The term “firmware” is apt for the software that is adapted to special tasks and that is developed for embedded systems. Essentially, it is about the close connection and interaction of flexible software with performance-optimized hardware. On the one hand, the firmware takes over the system control, and on the other hand the necessary system interaction with the environment. Three components determine design and functionality: boot loader, operating system and the application software specially written for the application.
Embedded software is software that was developed for specific hardware. This interactive reference is expressed in the term “firmware”. The finished product essentially consists of three components such as Bootloader, Operating system, and Application software. The increasing complexity in connection with today’s short product cycles determines the growing demands on the developers of hardware-integrated applications. In terms of optimal product solutions, the “embedded software” developers work together with the hardware department on the optimal implementation of device drivers and algorithms. Reliability and real-time behavior are the pillars of a successful embedded software solution. The particular challenge for the developer is to understand the functional complexity of the hardware product in question. This is the only way he will be able to program tailor-made software.
We encounter embedded software everywhere in everyday life, mostly in the form of so-called firmware. The functional applications control, regulate, and monitor various technical devices – largely unnoticed by the user. Because embedded systems are generally characterized by tight framework conditions. These include factors such as minimizing costs, space, storage, and energy requirements.
These restrictions often lead to processor platforms that differ significantly from the standardized PC computer world. On the other hand, there is often a requirement for real-time conditions as well as the highest level of security with regard to device operation and failure tolerance. The software design is based on these framework conditions.
Hardware-related programming not only requires knowledge of the programming languages used but also knowledge of compiler functions and know-how about operating systems and their structures. The share of embedded software development in the added value of a finished product has increased steadily in recent years. Embedded software has already taken on many product performance tasks today. Increasing functionality of electronic devices and the highest demands on user-friendliness are among the exciting challenges for hardware-related software specialists.
