As can be seen, a lot of research has been done for homogeneous platforms; comparatively, less has been done for heterogeneous platforms. As heterogeneous platforms are becoming more and more popular, energy-aware scheduling on heterogeneous platforms also needs further research focus. This chapter surveys existing works for energy-aware scheduling on heterogeneous platforms. It consists of three sections: frame-based tasks [26, 27], tasks with precedence constraints , and periodic tasks [30–33]. Actually, both  and  consider frame-based tasks and periodic tasks simultaneously; we put them under the category of periodic tasks. To the best of our knowledge, little has been done for energy-aware sporadic task scheduling on heterogeneous multiprocessor platforms.
