Abstract: A semiconductor device capable of reducing power consumption is provided. A group controller detects a zero weight parameter having a zero value among “n×m” weight parameters to be transferred to a weight parameter buffer. Then, when receiving the zero weight parameter as its input, the group controller exchanges the “n×m” weight parameters to be transferred to the weight parameter buffer so that all multiplication results of the “n” multipliers included in a target multiplier group that is one of the “m” multiplier groups are zero. The group controller controls the target multiplier group to be disabled, and exchanges the “n×m” pixel data to be transferred to the data input buffer, based on the exchange of the “n×m” weight parameters.
