最先进的移动的处理器可以提供快速响应时间和高吞吐量，以最大限度地提高用户体验。然而，高性能是以更大的功率密度为代价的，这导致更高的皮肤温度。由于这会降低用户体验，因此对移动的处理器中的功耗和热分析有强烈的需求。在本文中，我们首先在Nexus 6P手机上进行实验，以研究现代智能手机的功耗，性能和热行为。利用这些实验的洞察力，我们提出了一种控制算法，可以在不影响其他应用程序的情况下限制特定应用程序。我们在Odroid-XU 3板中使用的Exynos 5422处理器上演示了我们的调速器。
State-of-the-art mobile processors can deliver fast response time and high throughput to maximize the user experience. However, high performance comes at the expense of larger power density, which leads to higher skin temperatures. Since this can degrade the user experience, there is a strong need for power consumption and thermal analysis in mobile processors. In this paper, we first perform experiments on the Nexus 6P phone to study the power, performance and thermal behavior of modern smartphones. Using the insight from these experiments, we propose a control algorithm that throttles select applications without affecting other apps. We demonstrate our governor on the Exynos 5422 processor employed in the Odroid-XU3 board.
