This paper presents a prototype hardware/software architecture for minimizing energy consumption on high-end microcontrollers, while simplifying the development of applications providing a general-purpose-like programming environment. The key features enabling this twofold goal are operating system support to processes, optimized sensing and hibernation of the system state. To balance performance offered by high-end microcontrollers with the need for ultra-low power operation-especially required by WSNs - it is essential to minimize the duty cycle by keeping the microcontroller in a low-power state as long as possible, without affecting the performance required by the application.
