RePoMuC
Real-time Power management on partitioned MultiCores
| FCOMP-01-0124-FEDER-015050 PTDC/EIA-EIA/112599/2009 3 years (Feb 2011 to Jan 2014) | |
| Summary: | The fundamental objective of the RePoMuC project to provide a methodology for real-time power-management in Multicores, considering: 1. the non-linear behaviour of dynamic frequency and voltage scaling (DVFS) on execution-time and energy, 2. pre-emption delays, and 3. memory bus contention Particular focus will be given to demonstrate with a real-world implementation the practicality and limitations of the proposed methodology. The approach I intend to take is to build on successful experience of the group in the areas of DVFS power management, real-time multiprocessor scheduling and temporal isolation. The issues of DVFS behaviour, pre-emption delays, and memory bus contention have a fundamental communality in the sense that they are all tightly coupled to the amount of memory traffic. |
