Abstract: Based on analysis of Network on Chip (NoC) power model and mapping flow, a co-mapping algorithm based on genetic algorithm is proposed to minimize total communication power consumption. The algorithm automatically maps IP cores onto the NoC architecture combining IP selection and task assignment. Experiments are performed on various random benchmarks and a complex video/audio application to conform efficiency of the algorithm. The results show that the proposed algorithm saves on average 30% and 60% of power consumption, respectively, compared to the existing two-step mapping and the IP core-only mapping algorithms.
