Embedded Software Development

Using specific programming languages (like C and C++) to write code for a specific hardware device in which it runs is called embedded software development. It makes the device smart by performing actions based on user's input which improves the user experience. They are designed to perform function-specific tasks rather than doing multiple tasks like computers. The embedded system is incredibly intuitive. An embedded software system could be a system developed and organized on any device, apart from an old-fashioned computer. It is the brain of a specific device; however, it is a solely useless tool and simple to elucidate what software system is embedded.

Consider a system which employs an interrupt driven I/O for a particular device that transfer data at an average of 10 KBps on a continuous basis. Assume that interrupt processing takes about 100 µs (i.e. jump to the interrupt service routine (ISR); execute it and return to the main program).
