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.

Abstract: Disclosed is a method for synthesizing a diglyceride. The diglyceride is obtained by mixing a fatty acid donor with glycerol, partial glyceride lipase, and monoglyceride lipase by adding water, then subjecting the same to an esterification reaction, with a reaction time of 8 to 24 hours, and further separating and purifying the same. In the present invention, monoglyceride lipase is used to promote the reaction efficiency of partial glyceride lipase in the esterification reaction, so as to increase the synthesis rate of diglyceride. Compared with a single enzyme, the synthesis time is shortened by half or more, and 45.50% or more of diglyceride is obtained after the esterification reaction. Since substantially no triglyceride is generated in products, the content of DAG reaches 98% or more after the same has been purified by means of molecular distillation.
