摘　　要：通过分析基于AHB总线结构的master间传统的切换方法,提出了三种新的基于AHB总线结构的master间的切换方法,并给出了这些方法的关键电路的设计和仿真比较结果.对四种AHB总线master间的切换方法进行仿真,比较了各种方法的优劣,为在各种不同条件下,选择适当的master间的切换方法提供了详细依据.This paper, by analyzing the traditional master switch method based on the AHB bus architecture, putting forward three new master switch methods, and also giving the key circuit design of there method and making a comparison of the simulation results. For further more, in order to provide a comprehensive basis for readers selecting a appropriate method to the master switch in different conditions, the paper also gives out the simulation results of the four methods, and make an analysis of there results, and compares the advantages and disadvantages of there methods.
