The present disclosure relates to a data operation device and related products. The data operation device is used to perform multiplication operations on floating fixed-point numbers. The floating fixed-point numbers include exponents and significands. The data operation device includes: significand multiplication module , for multiplying the effective number of the first floating fixed-point number and the effective number of the second floating fixed-point number to obtain the undetermined effective number; The fixed-point number and the second floating-point number obtain the significand of the product and the exponent of the product; the product determination module is used to obtain the first floating-point number and the exponent of the product according to the significand of the product and the exponent of the product The product of the second floating-point numbers. The embodiments of the present disclosure can make the multiplication operation process of floating-point numbers efficient and the operation results accurate, and can reduce the area occupied by the multiplier in the chip on the basis of ensuring the range of data expression.
Description
technical field [0001] The present disclosure relates to the technical field of information processing, and in particular to a data computing device and related products. Background technique [0002] With the continuous development of information technology, there is an increasing demand for using computing devices to complete various computing tasks. In various calculation tasks, different data formats of the data to be calculated will have different effects on the calculation efficiency and calculation accuracy of the calculation device, and cannot meet the needs of different calculation tasks. For example, the data format of the data to be calculated can be a fixed-point number. For numbers with the same bit width, the representation range of the fixed-point number is negatively related to the precision. The area is larger. Contents of the invention [0003] In view of this, the present disclosure proposes a data operation device and related products to improve the p...
