Abstract

Achieving effective run-time mapping for Network on Chip (NoC) is a big challenge, particularly since the execution time and arrival order of applications are not known a priori. In this paper, we propose an energy-aware run-time mapping scheme, which consists of region selection algorithm and core mapping algorithm, for homogeneous NoC. The proposed scheme minimizes the energy consumption of the currently incoming application, and moreover, allows for additional applications to be easily added to the system with minimal energy consumption. Simulation results demonstrate the effectiveness of our proposed scheme in communication energy saving, when compared with the schemes in some previous work.
