【 摘 要 】

This work aims to adjust the energy consumed by hard real-time tasks, product variability of their execution times using integration of multirate control and feedback scheduling. Adapt and integrate dynamic techniques that handle the slack time due to the worst case execution time, update processor load factor and stretching of task to the next activation were adapted and integrated into Multirate Dynamic Technique for Management of Slack Time, lodged inpower aware real-time scheduler, to processors which vary the power voltage and operation frequency. In addition take advantage of multirate control techniques because resource management is formulated as a computer systems control problem that specifies each task by a control loop that works at their own activation period, other than those required in the reference and system response (processor total load factor). Results show that the slack time due to variability of the execution time is distributed naturally by multirate control loop, globally and locally, and can reach an energy saving of 61.04%, giving intra- interTask added value. It suggests a good performance to contrast it with other strategies.
