Abstract-- The Dynamic Voltage Scaling (DVS) technique
is the basis of numerous state-of-the-art energy management
schemes proposed for real-time embedded systems. However,
recent research has illustrated the alarmingly negative impact
of DVS on task and system reliability. In this paper, we consider
the problem of processing frequency assignment to a set of
real-time tasks in order to maximize the overall reliability,
under given time and energy constraints. First, we formulate the
