An ILP Approach to the Simultaneous Application of Operation Scheduling and Power Management

At the behavioral level, large power saving is possible by shutting down unused operations, which is commonly referred to as power management. However, on the other hand, operation scheduling has a significant impact on the potential for power saving via power management. In this paper, we present an integer linear programming (ILP) model for the simultaneous application of operation scheduling and power management in high level synthesis. Our objective is to maximize the power saving under both the timing constraints and the resource constraints. Compared with previous work, experimental data consistently show that our approach has significant improvement in the power saving.
