Abstract

The invention relates to a data conversion device and a related product, the device is used for converting a fixed point number into a floating fixed point number, the fixed point number comprises a symbol and an effective number, and the device comprises a highest non-zero bit determination module used for determining the number bit of the highest non-zero bit of the fixed point number effectivenumber; the index significant number determining module is used for determining the index of the floating point number and the significant number of the floating point number according to the number bit of the highest non-zero bit and the significant number of the fixed point number; and the floating point number determining module is used for obtaining the floating point number according to the symbol of the fixed point number, the index of the floating point number and the effective number of the floating point number. According to the embodiment of the invention, the fixed-point number canbe quickly and accurately converted into the floating fixed-point number. And compared with the fixed-point number, the floating fixed-point number improves the data representation range on the premise of ensuring the precision.

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...
