Abstract

This paper describes the system design of a low-power wireless camera. A system level approach is used to reduce energy dissipation and maximize battery lifetime. System properties such as the network configuration and data statistics are exploited to minimize computational switching. Embedded power supplies systems are also used to minimize energy dissipation under varying temperature, process parameters and computational workload. Since the camera operates in a burst mode with long idle periods, emphasis must be placed on reducing system standby power dissipation
