Trends in low power digital signal processing

System level optimization will be required for the implementation of ultra low power portable devices. Often, system properties such as data distribution or network configuration can be exploited to minimize computational switching. Embedded power supply systems configured in performance feedback also minimize energy dissipation under varying temperature, process parameters and computational workload. If the power dissipation of digital processors can be scaled to low enough levels, self-powered techniques can be used to achieve "infinite" lifetime and low-maintenance wireless operation.
