Abstract

This paper introduces ThermTap, which enables system and software developers to monitor the power consumption and temperature of various hardware components in an Android device as a function of running applications and processes. ThermTap comprises of a power analyzer, called PowerTap, and an online thermal simulator, called Therminator 2. With accurate power macro-models, PowerTap collates activity profiles of major components of a portable device from the OS kernel device drivers in an event-driven manner to generate power traces. In turn, Therminator 2 reads these traces and, using a compact thermal model of the device, generates various temperature maps including those for the device components and device skin. Fast thermal simulation techniques enable Therminator 2 to be executed in realtime. With precise per-process and per-application temperature maps that ThermTap produces, it enables software and system developers to find thermal bugs in their software. A case study is presented on identifying a thermal bug in the software running on an Android device.

ThermTap:用于Android设备的在线功率分析仪和热模拟器

本文介绍了ThermTap，它使系统和软件开发人员能够监控Android设备中各种硬件组件的功耗和温度，作为运行应用程序和进程的功能。ThermTap由一个名为PowerTap的功率分析仪和一个名为Therminator 2的在线热模拟器组成。通过精确的功率宏模型，PowerTap以事件驱动的方式从操作系统内核设备驱动程序中整理便携式设备主要组件的活动配置文件，以生成功率跟踪。反过来，Therminator 2读取这些迹线，并使用设备的紧凑热模型，生成各种温度图，包括设备组件和设备皮肤的温度图。快速热模拟技术使Therminator 2能够实时执行。通过ThermTap生成的精确的每个进程和每个应用程序的温度图，它使软件和系统开发人员能够发现他们软件中的热缺陷。本文介绍了如何识别在Android设备上运行的软件中的热bug的案例研究。
