Embedded Systems

Embedded systems are specialized computer systems that integrate hardware and software to perform a dedicated function within a larger mechanical or electrical product. Unlike a general-purpose computer, these systems are designed for specific tasks, often operating under real-time constraints and with limited resources for power, memory, and processing. As a cornerstone of computer engineering, the field involves the co-design of microcontrollers, sensors, and actuators with highly optimized software, or firmware, to create reliable and efficient devices. They are the hidden intelligence in countless applications, from automotive engine control and medical pacemakers to consumer electronics and industrial robots.
