A reconfigurable architecture for continuous mobile sensing

在移动计算领域，新兴的连续监测应用程序有可能彻底改变日常生活。虽然这些应用的处理需求在大多数情况下是适度的，但它们需要定期收集传感器读数。因此，执行连续传感的应用可能会导致设备电池在几个小时内耗尽。为了提高对连续传感应用的支持，华为加拿大公司将研究将传统处理器与一个或多个低功耗现场可编程门阵列（FPGA）相结合的异构架构的使用。在我们的方法中，传感应用的初始滤波阶段将被卸载到低功耗FPGA上。当运行在低功耗处理器上的代码检测到感兴趣的事件发生时，它将继续唤醒电话并将控制权传递给应用程序的其余部分。这个项目的研究阶段将需要设计和

In the area of mobile computing the emerging class of continuous monitoring applications has the potential to revolutionize everyday life. While the processing demands of these applications are modest most of the time, they require periodic collection of sensor readings. As a result, applications that perform continuous sensing may cause the devices battery to drain within several hours. To improve support for continuous sensing applications Huawei Canada will research the use of heterogeneous architectures that combine traditional processors with one or more low-power Field Programmable Gate Arrays (FPGA). In our approach, the initial filtering stages of the sensing application will be offloaded to the low-power FPGA. When the code running on the low power processor detects the occurrence of an event of interest, it proceeds to wake up the phone and passes control to the rest of the application. The research stage of this project will require the design and
