Network-on-Chip( NoC) mapping algorithm has significant impact on system power consumption,reliability and other performances. A new Multi-objective Mapping Immune Algorithm based on Energy and Reliability( MMIAER) is proposed to decrease power consumption and increase system reliability without additional overhead added. The MMIAER is constructed by designing a new antibody initialization operator and a new mutation operator based on basic immune algorithm. The new antibody initialization operator of MMIAER generates the initial antibodies by greedy algorithm,and therefore,the quality of the initial solutions is improved. The new antibody mutation operator reduces the communication distance and optimizes the solutions through exchanging positions of Intellectual Property( IP) cores,and therefore,the new antibody mutation operator decreases the degradation risk due to the randomness. With the dynamic character of the network, a new power consumption model is proposed to make the calculation of power consumption more accurately. Simulation results indicate that the MMIAER can decrease the power consumption and increase the system reliability effectively.
