Operation processing apparatus and operation processing method

An operation processing method for an operation processing apparatus that, by inputting input data to a hierarchical neural network and performing operation processing in each layer of the hierarchical neural network, calculates a feature plane in the layer, wherein

• the operation processing apparatus includes
• an operation unit,
• a feature plane holding unit including at least one memory that holds a feature plane to be processed by the operation unit,
• a memory access management unit configured to control to arrange the feature plane in the memory based on network information as information about each layer undergoing the operation processing and to manage reading/writing from/in the memory, and
• a processor configured to access, via a bus, the feature plane holding unit which is address-mapped in a memory space, and
• the processor calculates, based on the network information, an address address-mapped in the memory space, reads out the feature plane, and processes the feature plane.
