System Level Voltage Scheduling Technique Using UML-RT Model

In this paper, we present optimized methodology for Intra-task voltage scheduling. Our proposed method gets data flow and control flow of application that represents coloration between different parts of the application at the early stage of design using UML-RT model and decides to schedule processor's voltage. By applying this technique on JPEG encoder system experimental results show reduction in energy consumption by 18-54 % over common Intra-DVS algorithm.
