Embodiment Construction
[0061] The specific implementation of the power consumption and delay-oriented NoC mapping scheme search algorithm based on the discrete chaotic particle swarm optimization algorithm in the present invention is introduced below.
[0062] The mapping process includes two stages: PE selection and network node allocation, such as figure 1 shown. In the first stage, according to the power consumption delay data of tasks on heterogeneous PEs and the average network delay and average power consumption data, the optimal PE selection scheme is obtained by the chaotic discrete particle swarm algorithm. At this time, the high-level application includes a total of 8 tasks: T1-T8, and 6 available PE resources: PE1-PE6. In the second stage, based on the results of the first stage, the chaotic discrete particle swarm algorithm is used to obtain the final mapping result from the PE to the NoC network platform using accurate delay and power consumption parameters.
