Energy consumption is a major concern in modern real-time embedded systems and leakage current is a main contributor to it. To deal with the leakage current, several procrastination approaches have been proposed in the past in order to reduce the energy consumption. These approaches approximate the procrastination interval for the ease of analysis and sub-optimally utilise the potential to reduce the energy consumption. This paper presents an optimal method to determine the procrastination interval of each task and generalise the task-model to cover the constrained deadline tasks. Analytical and experimental results show the superiority of the proposed technique. In the best case, the proposed technique extends the average sleep interval up to 75% and decreases the energy consumption in idle state up to 55% over the state-of-the-art.
