Abstract
Provided is a device configured to perform a convolution operation. The device includes bi-directional First In First Out memory including bi-directional latches configured to transfer data in a first direction or a second direction depending on a clock signal and connected to each other and performs a convolution operation of an input value and a filter. The device stores first input values corresponding to a window equivalent to a size of the filter from a input value matrix in the bi-directional First In First Out memory in response to a first convolution operation and stores second input values corresponding to a location of the window which is moved in the first direction or the second direction by a predetermined amount from locations of the first input values in the bi-directional First In First Out memory in response to a second convolution operation subsequent to the first convolution operation.
