    Traditional embedded systems employ a time-triggered scheduler or an event-triggered scheduler, however, the truth is that time-triggered scheduling architecture is more dependable but lack of responsiveness to external events and event-triggered scheduling architecture is responsive. In order to get those advantages at the same time, a real-time kernel with a hybrid scheduler, named SinewOS, is d... View full abstract»

    A number of approaches have been proposed so far for reducing the energy consumption of embedded systems by using scratch-pad memory. However, most of previous work focused on dynamic energy reduction, and did not take enough consideration of the leakage energy in their evaluations. As the technology scales down to the deep submicron domain, the leakage energy in memory devices could contribute to... View full abstract»
