Processing device of a neural network to process image data

A data processing method of a computer system for processing input image data, the computer system including a memory and a processer configured to execute an operation of a neural network using data stored in the memory, the neural network comprising a plurality of processing devices including a first processing device and a second processing device, the data processing method comprising:

• receiving input data including the image data;
• executing, by the first processing device, first processing using a first matrix indicated as an equation (Q1) to first data of a size of 5×5 within the received input data to generate second data;
