Abstract: A depth-wise convolution acceleration device using an MAC array processor structure according to the present invention may include a data output unit, which receives a data of each row of the image from the data buffer and inputs the data into convolution operation blocks while shifting the data N?1 times according to the kernel size (N×N) and a weight output unit, which receives the kernel data from the kernel buffer and sequentially inputs a weight value constituting the kernel data to each of the row convolution operation blocks, and inputs the weight delaying by N clocks if the row increases as N rows.

Abstract: Methods and terminals for sharing content are described. In one method, an application is activated, upon detection of an event for executing the application, on a terminal, and an application screen having at least one content is displayed. Upon detecting a touch input for selecting, at least one content is selected. Upon detecting a touch input on a transmission button on the application screen, the selected at least one content is transmitted to an external terminal. In another method, an application screen having at least one icon for executing function is displayed; a touch input for selecting an icon associated with content to be received from an external terminal is detected; at least one identifier broadcast by the external terminal is displayed; and at least one content is received from the external terminal corresponding to the selected identifier, upon detection of a touch input for selecting at least one identifier.
