Title: Frequency and voltage scaling in real-time systems
Subject: Computer Science
Level: Basic or Advanced (contact supervisor)
Description: Energy management is an important issue in real-time systems where energy is a scarce resource. There exist many techniques for energy management in real-time systems. Dynamic Voltage Scaling (DVS) is an attractive technique typically used to reduce the overall energy consumption by reducing the voltage and frequency of the processor, while preserving the real-time guarantees. Another potential application of DVS in real-time systems is to influence the execution pattern of tasks in order to achieve a required real-time behavior, e.g., with respect to preemptions, jitter, etc. However, this is not trivial as DVS for energy management in real-time systems may lead to deadline misses in the schedule. This typically occurs due to the increase in task execution times resulting from the lower CPU frequency. The aim of the thesis is to develop and implement DVS techniques on a real-time platform, i.e., EVK 1100, to control the real-time behavior of the system while provide for trade-offs regarding the energy consumption.
