Energy Efficient Block-Partitioned Multicore Processors for Parallel Applications

Energy management has become an important research area in the last decade. As an energy efficient architecture, multicore has been widely adopted. However, with the number of cores on a single chip continuing to increase, it has been a grand challenge to effectively manage the energy efficiency of multicore-based systems. In this paper, based on voltage island and Dynamic Voltage and Frequency Scaling (DVFS) techniques, the authors investigate the energy efficiency of block-partitioned multicore processors, where cores are grouped into blocks and each block has a DVFS-enabled power supply. Depending on the number of cores on each block, they study both symmetric and asymmetric block configurations.
