Abstract
Reliability-aware power management (RAPM)
schemes, which consider the negative effects of voltage
scaling on system reliability, were recently studied to
save energy while preserving system reliability. The
existing RAPM schemes for periodic tasks may be, how-
ever, inherently unfair in that they can manage only some
tasks at the expense of the other remaining tasks. In this
work, we propose the flexible reliability-aware power
management framework, which allows the management
of all the tasks in the system, according to their assurance
requirements. Optimally solving this problem is shown
to be NP-hard in the strong sense and upper bounds
