Title:
DATA PRE-LOADING APPARATUS AND DATA PRE-LOADING METHOD, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/021459
Kind Code:
A1
Abstract:
Disclosed are a data pre-loading apparatus and a data pre-loading method, and a storage medium. The data pre-loading method comprises: acquiring an original data set and a zero-padded data set, wherein the original data set and the zero-padded data set jointly form an input data set of a convolutional neural network; and before calculation units perform convolution calculation, storing, according to a predetermined allocation mode, data in the input data set in caches corresponding to the calculation units, so as to respectively form different target data sets in the caches of the calculation units, wherein data in the target data sets is data required by the calculation units during a convolution calculation process. Temporal sorting or spatial sorting is performed on original data and zero-padded data, an input data set is formed, and pieces of data in the input data set are allocated to caches of different calculation units, so that the data reusability is improved, the memory reading frequency is reduced, the data preparation time is shortened, the delay between layer calculations is reduced, and the overall power consumption of a chip is reduced.
