The embedded software engineering definition is as follows-
Embedded Software Engineering is the process of controlling various devices and machines that are different from traditional computers, using software engineering. Integrating software engineering with non-computer devices leads to the formation of embedded systems. Embedded systems are typically popular in medical science, consumer electronics, manufacturing science, aviation, automotive technology. A typical embedded system requires a wide range of programming tools, microprocessors and operating systems. Embedded software engineering, performed by embedded software engineers, needs to be tailored to the needs of the hardware that it has to control and run on.
Now that we have the answer to “what is embedded engineering”, let us understand what are the requirements of embedded systems, which includes the software for embedded systems. The software and operating system requirements of an embedded system is also different from a traditional computer based system. Typically embedded systems use basic embedded system software such as C, C++, ADA, etc. Some specialized embedded systems may use OS such as Windows CE, LINUX, TreadX, Nucleus RTOS, OSE, etc.
Embedded software engineering differs from traditional application development in terms of the additional consideration to external factors such as temperature and other environmental factors that may affect performance.
