无线传感器节点（WSN）在医疗保健和生活方式监测方面有着广泛的应用。它们严重的能量限制通常是通过节能的节点信号处理最大限度地减少传输数据量来解决的。这种方法的基本原理是，即使在数据速率非常低的情况下，无线传感器网络的大部分能量也被无线电通信消耗[1]。高效的节点上处理一直是最近工作的主题，其共同要素是将电压缩放到亚阈值区域 [2-4]。现有工作的一个主要假设是所需的计算量较低，证明节点上处理器的计算能力有限。虽然无线传感器网络的许多应用可能都是这种情况，但新兴的动态生物医学信号处理应用超出了当今节点处理器提供的性能。
Wireless Sensor Nodes (WSN) have a wide range of applications in health care and life style monitoring. Their severe energy constraint is often addressed through minimizing the amount of transmitted data by way of energy-efficient on-node signal processing. The rationale for this approach is that a large portion of WSN energy is consumed by the radio communication even for very low-data-rate situations [1]. Efficient on-node processing has been the subject of recent work, with the common element being aggressive voltage scaling into the sub-threshold region [2-4]. A major assumption of the existing works is that the amount of required computation is low, justifying an on-node processor with limited computational capability. While this might be the case for many applications of WSNs, emerging ambulatory biomedical signal processing applications exceed the performance offered by today's on-node processors.
