Embedded Systems
Embedded systems represent the convergence of hardware and software, creating dedicated computing solutions optimized for specific tasks. Unlike general-purpose computers, embedded systems are designed to perform predetermined functions with real-time constraints, power efficiency, and reliability requirements that shape every aspect of their architecture.
From simple microcontrollers in household appliances to sophisticated systems-on-chip powering autonomous vehicles, embedded systems form the invisible computational infrastructure of modern life. This category explores the fundamental concepts, architectures, and design methodologies that enable engineers to create efficient, reliable, and purpose-built computing solutions.
