Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] Such as figure 1 As shown, the present invention divides the software execution process into several program segments according to the process switching through the CPU simulator, and then counts the characteristic parameters of each program segment, so that each software will output multiple sets of characteristic parameters to form a multi-dimensional feature A matrix of parameters. Extract typical program fragments from the feature parameter matrix, use the SOM clustering algorithm to find out how many different types of feature fragment clusters the software load feature contains from many program fragments, and then use the K-means clustering algorithm to extract the same type of feature fragment clusters Find the program fragment that best represents the characteristics of this cluster.
