Power-Aware Dynamic Memory Management on Many-Core Platforms Utilizing DVFS IRAKLIS ANAGNOSTOPOULOS, National Technical University of Athens JEAN-MICHEL CHABLOZ, Royal Institute of Technology - KTH IOANNIS KOUTRAS and ALEXANDROS BARTZAS, National Technical University of Athens AHMED HEMANI, Royal Institute of Technology - KTH DIMITRIOS SOUDRIS, National Technical University of Athens Today multicore platforms are already prevalent solutions for modern embedded systems. In the future, embedded platforms will have an even more increased processor core count, composing many-core platforms. In addition, applications are becoming more complex and dynamic and try to efficiently utilize the amount of available resources on the embedded platforms. Efficient memory utilization is a key challenge for application developers, especially since memory is a scarce resource and often becomes the system's bottleneck. To cope with this dynamism and achieve better memory footprint utilization (low memory fragmentation) application developers resort to the usage of dynamic memory (heap) management techniques, by allocating and deallocating data at runtime. Moreover, overall power consumption is another key challenge that needs to be taken into consideration. Towards this, designers employ the usage of Dynamic Voltage and Frequency Scaling (DVFS) mechanisms, adapting to the application's computational demands at runtime. In this article, we propose
