交互式可穿戴设备为应用程序和硬件带来了巨大的更改,将操作系统(OS)设计留在薄雾中。为此,我们彻底检查了流行的可穿戴操作系统Android Wear的执行效率。通过运行一套15个基准的套件,我们介绍了四个系统方面:CPU使用,空闲插曲,线程级并行性和微体系构造行为。我们介绍发现的低效率及其根本原因,以及一系列普遍但未知的OS设计缺陷。为了设计未来的可穿戴OS,我们的研究提供了通用的课程,关键的见解和特定的动作项目。
Interactive wearable devices bring dramatic changes to apps and hardware, leaving operating system (OS) design in the mist. To this end, we thoroughly examine the execution efficiency of Android Wear, a popular wearable OS. By running a suite of fifteen benchmarks, we profile four system aspects: CPU usage, idle episodes, thread-level parallelism, and microarchitectural behaviors. We present the discovered inefficiencies and their root causes, together with a series of widespread, yet unknown OS design flaws. Towards designing future wearable OSes, our study has yielded a generic lesson, key insights, and specific action items.
