This project addressed the system-on-a-chip implementation of a PicoNode, which can provide all the communication, computation, and geolocation functions necessary for an adaptive distributed sensor-and-monitor network. The program embodied many key principles of DARPAs initiatives in advanced computing, including adaptive computing and power-awareness. The program explored three complete design cycles. Sixty units of PicoNode I 460mW, 18cu.in. were built. The chip-set for PicoNode II was functionally demonstrated, and a test-board was constructed. At 15mW, the chipset of the second generation represented a 23X improvement over the first generation. Significant progress on the final generation was achieved, including an FPGA version and an energy scavenging power train. Project goals of the final system 0.15 cu.in. 30x improvement and 1 mW 460x improvement.
