Embedded Software Development

What is Embedded Software Development?

Embedded software development involves creating specialized programs that run on embedded systems—computers integrated into devices that perform dedicated functions. Unlike general-purpose software, embedded systems have specific constraints like low power consumption, limited memory, and real-time processing. These systems are used in devices such as automobiles, medical devices, industrial machines, IoT devices, and consumer electronics.
