2. 2 What is Evolvable Hardware Evolvable Hardware (EHW) is a new field at the confluence of Automatic Design, Artificial Intelligence, Reconfigurable Hardware, and Autonomous Systems. Its main objective is the development of flexible and survivable capable of intelligent self-configuration, self-tuning, and self-repair, that can adaptively change through reconfiguration or compensation to provide optimal signal processing, sensing and control, as well as survival in the presence of faults and degradation due to harsh environments. EHW techniques have already proven successful in automated design, automated calibration and tuning, and in-field adaptation of hardware systems, sensing, control and robotics.

3. 3 Course Content This course: –presents the fundamentals of EHW technology, –reviews existing and previews future reconfigurable devices, –explains algorithms and techniques for guiding automated design, optimization and self-configuration –illustrates operation with evolution-guided design and hardware self-configuration experiments, –provides application examples, and –covers specific difficulties and solutions for evolving complex systems and doing evolution with hardware in the loop.

4. 4 Intended Audience The course is intended for engineers, managers, and other professionals who are involved in automated design, system optimization, and intelligent and adaptive hardware. It addresses issues needed in the development of autonomous systems, automatic calibration, and tuning. At the end of the course, participants should be able to design an evolution-driven optimization or evolvable hardware system for their particular area of application.
