The research on system-level modeling technology of mixed-level abstraction
Yukun Song, Kuai Cao, Duoli Zhang · 2014
Firstly, this paper introduces the classification of different abstraction level of system model and puts forward these questions needed to be solved during the establishment of system model. Secondly, it gives the analysis of the advantages and disadvantages of all existing solutions and implements the modeling based on the method of interface encapsulation. Thirdly, the paper elaborates the merits of this method, such as strung expandability, less memory usage, simple communication, etc., and introduces the concrete implementation of key parts of interface encapsulation. Finally, the paper take heterogeneous multi-core system as an example where the data communication and data processing among mixed abstraction level model have been implemented. The mixed-level model ameliorates efficiency of the model simulation evidently. The result of experiments proves that the average time saving rate of simulation of the system model of mixed abstract level reaches 92.68%.
