発明の名称 (英語) ARITHMETIC OPERATION DEVICE AND ARITHMETIC OPERATION SYSTEM UPDATE 新技術説明会
発明の概要(英語) Provided is an arithmetic operation device provided with: a multiplication section in which a plurality of multipliers are divided in units of one or more multipliers in accordance with an arithmetic operation accuracy mode and allocated to one or more groups, and in each of the groups, each multiplier multiplies an individual multiplier factor within at least a partial digit range of a multiplier factor for the group by an individual multiplicand within at least a partial digit range of a multiplicand for the group in accordance with the arithmetic operation accuracy mode; and an addition section in which a plurality of adders are divided in units of one or more adders in accordance with the arithmetic operation accuracy mode and allocated to one or more groups, and the one or more adders allocated to each of the groups add together the multiplication results of the respective multipliers allocated to the group, and output a product of the multiplier factors and the multiplicands.
