Low power process assignment for distributed embedded systems using dynamic voltage scaling

This paper presents an efficient algorithm for voltage scaling of a distributed embedded system taking communicating processes into account. The algorithm finds scaled voltages for each processes without restricting the applicable voltage levels a priori. In addition the algorithm is not limited by a fixed power consumption among processes. Furthermore we show the importance of a process optimisation which is optimised for the dynamic voltage scaling (DVS) technique. Various examples from the literature and randomly generated show the efficiency of the proposed scaling algorithm and the DVS optimised process assignment. (4 pages)
