Abstract :
Low energy consumptions are extremely important in real-time embedded systems, and scheduling is one of the techniques used to obtain lower energy consumptions. In this paper, we propose loop scheduling algorithms for minimizing energy based on rotation scheduling and DVS (dynamic voltage and frequency scaling) for real-time multi-core embedded systems. The experimental results show that our algorithms have better performances than list scheduling and pure ILP (integer linear programming) scheduling with DVS
