Abstract
Disclosed is a neural network accelerator including a maximum value determiner outputting a maximum value based on a first magnitude component corresponding to first input data and a second magnitude component corresponding to second input data, a sign determiner outputting a sign component corresponding to the maximum value among a first sign component corresponding to the first input data and a second sign component corresponding to the second input data, as an output sign component, an offset operator quantizing a difference between the first magnitude component and the second magnitude component and outputting an output offset based on the first sign component, the second sign component, and the quantization result, and a magnitude operator calculating an output magnitude component of an output data based on the maximum value and the output offset. Each of the first input data and the second input data is data on a logarithm domain.
