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-datarate situations [1]. Efficient on-node processing has been the subject of recent work, with the common element being aggressive voltage scaling into the subthreshold 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
