| Abstract: | The problem of energy-aware mapping for network-on-chip(NoC) implemented with voltage islands under reliability constraints is formulated.A tabu search algorithm is proposed to solve this problem.A novel energy-efficiency gradient driven heuristic is developed to assign the voltages for the voltage islands based on the current configuration of IP mapping during global design space exploration.Experimental results show that the proposed method can efficiently guarantee the reliability goal and obtain signifi... |
