现代片上系统（SoC）集成了CPU和GPU，可提供身临其境的3D游戏体验。这些游戏需要CPU和GPU协同工作，从而导致高功耗。过去，动态电压频率缩放（DVFS）已被用于嵌入式CPU，以在游戏过程中节省功耗;但直到最近，嵌入式GPU才获得DVFS功能，从而提供更多机会。在本文中，我们提出了一种电源管理方法，采取统一的看法，CPU-GPU DVFS，从而降低功耗为最新的3D手机游戏相比，一个独立的CPU-GPU电源管理方法。
Modern system-on-chips (SoC) integrate CPU and GPU for immersive 3D gaming experience. These games require both the CPU and GPU to work in tandem, resulting in high power consumption. In the past, Dynamic Voltage Frequency Scaling (DVFS) has been exploited for embedded CPU to save power during game play; but it is only recently that embedded GPUs have attained DVFS capabilities that provide additional opportunities. In this paper, we propose a power management approach that takes a unified view of the CPU-GPU DVFS, resulting in reduced power consumption for latest 3D mobile games compared to an independent CPU-GPU power management approach.
