Coarse-grained reconfiguration: dataflow-based power management

Power reduction in modern embedded systems design is a challenging issue exacerbated by the complexity and heterogeneity of their architecture. In the field of Reconfigurable Video Coding (RVC), to challenge these issues and cut-down time to market, dataflow-based techniques have been adopted. In particular, to master management and composability of dynamically reconfigurable systems, the authors have developed the multi-dataflow composer. Nevertheless, despite the RVC offers several different tools, in its reference design framework power management is still an open issue. To make some steps forward towards filling this gap, in this study, they address power management for coarse-grained reconfigurable systems combining structural and dynamic strategies, both to be applied at the dataflow level.
