An object is to provide an information processing apparatus capable of preventing utilization percentage of PEs from decreasing in a series of processes in CNN. An information processing apparatus (1) according to the present disclosure includes a PE (Processing Element) Grid (20) configured to perform a convolution by using a plurality of Kernels for Input matrix data and thereby generate a different Output matrix data for each of the used Kernels, the PE Grid (20) including a plurality of PEs configured to calculate pixels constituting the Output matrix data, and a Parallelism Controller (10) configured to determine, based on the Input matrix data or a dimension of the Output matrix data, and the number of the Kernels, whether pixels included in respective Output matrix data should be parallelly calculated or a plurality of pixels included in one Output matrix data should be parallelly calculated.
