Abstract
A CNN processing apparatus () includes an input buffer () configured to store an input signal A given to a CNN, a weight buffer () configured to store weights U, a convolutional operation unit () configured to perform a convolutional operation including a product-sum operation of the input signal A and the weights U, a storage unitconfigured to store a table () which is configured to associate an input and an output of conversion-quantization processing with each other, wherein the input is an operation result of the convolutional operation, and the output is a result of the conversion-quantization processing of converting the input value based on a predetermined condition and quantizing the converted value by reducing a bit accuracy of the converted data, and a processing unit () configured to acquire the output of the conversion-quantization processing corresponding to the operation result by the operation unit by referring to the table ().
