Abstract

The invention provides a compression method and device of neural network data and a computer readable storage medium, and the method comprises the steps: receiving to-be-compressed data which is the activation output of any layer of a neural network model; determining a plurality of data blocks according to the to-be-compressed data and a preset data length; and performing compression operation onthe plurality of data blocks according to a bit plane compression algorithm. By utilizing the method, the to-be-compressed data is converted into the plurality of data blocks, and the data blocks arecompressed by adopting the bit plane compression algorithm, so that a relatively high compression rate can be realized, the storage space can be saved, and the memory access efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of neural network data compression, and in particular relates to a neural network data compression method, device and computer-readable storage medium. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the rapid development of the neural network, the recognition accuracy of the neural network model is continuously improved, and the scale of the neural network is also increasing. The demand for storage space and memory bandwidth is also increasing. On the one hand, this leads to an increase in storage costs. On the other hand, it leads to a decrease in the on-chip and off-chip memory access efficiency of the neural network chip, which affects the data processing performance of the neural network. [0004] There...
