The HW/SW codesign group at the Institute for Technical Informatics deals with embedded systems, HW/SW codesign, and power awareness. Design of embedded systems can be subject to many different types of constraints, including timing, size, weight, power consumption, reliability, and cost. Research on HW/SW codesign is done since the early 90s. With each new process technology systems with much higher complexity can be implemented on a single die. This requires new methodologies to abstract the system and to handle the design complexity. HW/SW codesign is a set of methodologies and techniques specifically created to support the codesign of hardware and software systems.
