论文摘要
对较大的触摸屏面板(TSP)的需求不断增长,以传统的传感方法为移动系统增加了更多的能源负担。为了减轻此问题,利用触摸事件的稀疏性,本文提出了一个新颖的TSP读数系统,当没有激活传感器时,可以通过关闭读取电路来获得巨大的节能。为此,提出了一个基于轻量压缩感应的新型超低功率始终启用事件和感兴趣的检测区域。提出了利用所提出的事件检测器,可以提出上下文感知的TSP读数系统,该系统可以提高能源效率高达42X。
Increasing demand for larger touch screen panels (TSPs) places more energy burden to mobile systems with conventional sensing methods. To mitigate this problem, taking advantage of the touch event sparsity, this paper proposes a novel TSP readout system that can obtain huge energy saving by turning off the readout circuits when none of the sensors are activated. To this end, a novel ultra-low-power always-on event and region of interest detection based on lightweight compressed sensing is proposed. Exploiting the proposed event detector, the context-aware TSP readout system, which can improve the energy efficiency by up to 42x, is presented.
