The communication problem in modern ICs becomes a challenge issue. This paper introduces a high-level mapping algorithm targeting to low-power 3D NoC devices. By appropriately assigning application's functionalities to layers with different supply voltages we achieve reasonable energy savings and temperature reduction. Additionally, our methodology supports real-time adaption on different traffic scenarios. Experimental results show that energy savings up to 19% are feasible, without any area and delay overhead, as compared to architectures powered by only one supply voltage.
