Abshact-Harvesting energy from environmental sources can extend wireless sensor network node lifetime beyond the limits of battery technology. However, the output power from an energy harvester is highly variable. We propose a domain-specific computational array which maximizes sensor performance by matching system power consumption to the available(More)
Low power signal processing functionality is required for wireless sensor network nodes due to their limited battery life. Previously, we have proposed a recon¿gurable array of DSP acceleration functional units for such a sensor node. The array maximizes operating life by matching system power consumption to available energy through power scalable(More)
A full-swing on-chip interconnect using pulse width modulation (PWM) was designed and fabricated in 0.25μm CMOS for application in a tiled signal processing array architecture targeting wireless sensor nodes. Measurements show a decrease in the worst case power of 7% over traditional binary signaling for 11.8mm long wires at 10Mbps throughput and 0.7V(More)
