Abstract

The disclosure relates to a data conversion device and related products. The device is used to convert a fixed-point number into a floating-point number. The fixed-point number includes a sign and an effective number. The device includes: the highest non-zero bit determination module for Determine the digit of the highest non-zero digit of the fixed-point number effective number; the exponent effective number determination module is used to determine the exponent and the fixed-point number of the floating fixed-point number according to the highest non-zero digit and the effective digit of the fixed-point number The effective number of the floating fixed-point number; the floating fixed-point number determination module obtains the floating fixed-point number according to the sign of the fixed-point number, the exponent of the floating fixed-point number and the effective number of the floating fixed-point number. The embodiments of the present disclosure can quickly and accurately convert fixed-point numbers into floating-point numbers. Compared with fixed-point numbers, floating-point numbers improve the range of data representation under the premise of ensuring accuracy.

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 computing devices using neural networks to complete complex tasks. The neural network computing device may include different types of circuit structures, and different circuit structures are suitable for different computing processes and have different processing efficiencies. For example, the neural network computing device includes a master-slave circuit structure. Multiple slave processing circuits perform calculations at the same time, and the main processing circuit obtains the final calculation result after all the slave circuits complete calculations, and the overall calculation efficiency is low. Contents of the invention [0003] In view of this, the present disclosure propose...
