eRTOS : The low-power real-time operating system for wearable computers
A wearable computer is a computer that is subsumed into the personal space of the user, controlled by the user, and is always on and always accessible. Therefore, among the most salient aspect of wearable computers should be small form factor and long battery lifetime. In this paper, we have designe...

| description | A wearable computer is a computer that is subsumed into the personal space of the user, controlled by the user, and is always on and always accessible. Therefore, among the most salient aspect of wearable computers should be small form factor and long battery lifetime. In this paper, we have designed and implemented a low-power real-time operating system (called ldquoeRTOSrdquo) specialized for wearable computers. eRTOS has about 9 KB footprint and is equipped with low-power techniques composed of the dynamic power management and the device power management. Experimental results with wearable applications show that we can save energy up to 47% using the proposed low-power techniques. |
