NOEUD MATÉRIEL AYANT UNE UNITÉ DE VECTEUR DE MATRICE AVEC TRAITEMENT DE VIRGULE FLOTTANTE PAR BLOC

摘要

Processors and methods for neural network processing are provided. A method includes receiving vector data corresponding to a layer of a neural network model, where each of the vector data has a value comprising at least one exponent. The method further includes first processing a first subset of the vector data to determine a first shared exponent for representing values in the first subset of the vector data in a block-floating point format and second processing a second subset of the vector data to determine a second shared exponent for representing values in the second subset of the vector data in a block-floating point format in a manner that no vector data from the second subset of the vector data influences a determination of the first shared exponent and no vector data from the first subset of the vector data influences a determination of the second shared exponent.
