Analyses of rate of Zero value and time consumptionreveal redundancy covolutional computation and are assumedcomputational volume reduction of CNN. Average rates ofZero value in convolution layers are 35% and 55%, For fullyconnection layers, the average rates are 47% and 33%. it isproved by redundancy computation. Largest time consumptionis conv1 layer, and this time is about 3 times larger than secondone for the reason of the total number of multiplications.By reducing the redundancy, with faster execution speed, itcan be led performance efficiency of CNN can be improved.
