Abstract：Reconfigurablearrayarchitecturescombinetheflexibilityof general-purposeprocesors withthehigh energyefficiencyof dedicated hardware，making themanidealsolution forcomputation-and memory-intensiveapplications suchasconvolutional neuralnetwork（CNN）.However，ncreasingcomputationaldemandsaisememoryacessoverhead，itingeficiencygains.Toaddressthis，thispaperproposeda CNN-orientedmultidimensionaldatareuse method forreconfigurablearrays.Byutilizing intra-computing-unitdata cyclicreuseandinter-unitdata pulsationtransfer，itachieveddatareuseacross bothcomputingunitsandarraydimensions.Taskswitching wasenabledthrougharryreconfigurationtofacilitatemultidimensional datareuse.Experimentalresultsonthe VirtexUltraScale440board showthatthis methodreduces memoryaccess byup to 69.4% ，improves computational speed byover 16.2% ，and achievesa computingunitutilizationrateof 94.1% .These results demonstrate thathis method enhances datareuseforCNNonreconfigurablearrys，enabling eficienthardware acceleration.
