Abstract: A neural network circuit 201 is a neural network circuit divides convolution operation into convolution operation in a spatial direction and convolution operation in a channel direction, performs the respective convolution operation separately, and includes a 1×1 convolution operation circuit 10 that performs convolution in the channel direction, an SRAM 20 in which a computation result of the 1×1 convolution operation circuit 10 is stored, and an N×N convolution operation circuit 30 that performs convolution in the spatial direction for the computation result stored in the SRAM 20.
