What is Embedded Application Development?

What Defines an Embedded Application?

The purpose of an embedded application is to run specifically on embedded systems. The software exhibits a strong connection with hardware while it receives optimization for reliability, performance, and efficiency targets. 

Embedded applications run in real-time systems through which users have restricted control over execution times. These applications serve a single functional requirement or a limited number of tasks and find their use in the automotive sectors and medical and consumer electronic industries.

Key Components of an Embedded System

Here are seven components of an embedded system:
