Problems solved by technology

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. larger area

Abstract

The disclosure relates to a data operation device and related products. The device is used for the addition operation of floating-point numbers, and the floating-point numbers include exponents and significant numbers. The device includes: a judging module for determining the first floating-point number The larger number and the smaller number in the point number and the second floating fixed-point number; and a significant number determination module, which is used to shift the significant number of the smaller number, and shift the effective number and the smaller number of the smaller number after the shift. The significant number of the large number is added to the bit to obtain the result of the addition of the bit; and the determination module is used to obtain the index of the sum according to the result of the addition of the bit and the exponent of the larger number, and to obtain the index of the sum of the result of the addition of the bit according to the result of the addition of the bit. Gets the sum of the first floating-point number and the second floating-point number. In the embodiment of the present disclosure, the determination of the larger number and the smaller number and the displacement of the effective number of the smaller number can make the addition operation process of the floating fixed-point number efficient and the operation result accurate. On the basis of ensuring the range of data expression, the area occupied by the adder in the chip can be reduced.

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...
