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.
