The problem of reducing energy consumption is dominating the design of several real-time systems.
The Dynamic Voltage Scaling (DVS) technique, provided by most microprocessors, allow to balance
computational speed versus energy consumption.
We present some novel energy-aware scheduling algorithms that allow to expoit this technique while
meeting real-time constraints. In particular, we present the GRUB-PA algorithm which, unlike most
existing algorithms, allows to reduce energy consumption on real-time systems consisting of any kind of task.
We also present a working implementation of the algorithm on Linux
