Abstract
This paper proposes a new hardware-based energy management technique for future embedded multithreaded processors with integrated Earliest Deadline First (EDF) real-time scheduling. Our energy management technique controls frequency reduction and dynamic voltage scaling depending on the deadlines, the Worst Case Execution Times (WCET), and the real execution times. Hard real-time capability can be guaranteed for aperiodic threads and for threads with deadlines shorter than their period. Our evaluations show that energy consumption can be reduced up to about \(\frac{2}{3}\) of a comparable software-based algorithm.
