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.
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. When the fixed-point number is used for calculation, there may be a problem of insufficient representation range.

Abstract

The invention relates to a data conversion device and a related product, and the device is used for converting a floating point number into a fixed point number, and comprises a fixed point number significant number determination module which is used for determining an undetermined significant number according to an index and a significant number of the floating point number; And the fixed-point number acquisition module is used for determining the fixed-point number according to the sign of the floating fixed-point number and the undetermined effective number. According to the embodiment of the invention, the floating point number can be quickly and accurately converted into the fixed point number. And compared with the fixed-point number, the data representation range is improved on thepremise of ensuring the precision of floating fixed point number.

Description

technical field [0001] The present disclosure relates to the technical field of information processing, in particular to a data conversion 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. 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. When the fixed-point number is used for calculation, there may be a problem of insufficient representation range. Contents of the invention [0003] In view of this, the present disc...
