摘　　要：随着芯片集成度的提高,网络通信流量与通信功耗也随之递增.片上网络在设计阶段就要考虑到通信功耗问题,因此提出一种可以降低通信功耗的映射方法,该方法是一种改进的最大最小蚁群算法,通过优化权重系数、状态转移规则以及信息素更新来提高算法的性能.实验表明,该方法能加速搜索进化过程,避免搜索的停滞,具有较好的收敛性,能有效的降低系统的映射功耗.Traffic and power of communication on chips has been increasing with the improvement of chip integration. The power consumption must be considered in the stage of design. The new mapping algorithm is proposed on how to reduce the communication power on No C. The improved max-min ant system method can get a better performance by updating the pheromone, optimizing the weight coefficients and the state transition rules. Experimental results showed that the proposed algorithm could reduce the power consumption of the system with the compared method and had a good convergence which could accelerate the search process and avoid the stagnation.
