Embodiment
[0029] Such as figure 1 As shown, the LRU Cache prefetching mechanism performance benefit evaluation method based on artificial neural network of the present invention, concrete realization can comprise the following steps:
[0030] (1) Extraction of artificial neural network training set:
[0031] Artificial neural network training needs multiple sets of training data as input to complete the training of neuron weight coefficients. The present invention cuts the complete application program into several program fragments, and extracts two types of information from each program fragment, one is the stack distance distribution before the prefetch mechanism is added, and the other is the number of cache access misses after the prefetch mechanism is added .
[0032] (2) Selection of artificial neural network topology and neuron weight training method:
[0033] The selection of artificial neural network topology and neuron weight training method is realized by traversing all th...
