Abstract

A data compression, decompression method, and an electronic device. The method includes the following steps: establishing an initial lookup table by using data with the same value in dataset to be compressed as one index, sequentially building a new Huffman tree corresponding to each index, and then adding a separator to obtain an encoding list containing a target encoding value and length, adding the encoding list to the initial lookup table to obtain a target lookup table. According to a separator of bitstream data, and searching the target lookup table in parallel, and use the indexes to obtain the decompression result of the data to be decompressed. Embodiments can perform a parallel decompression operation to increase a decompression speed, so that the decompression speed can meet the requirement of an AI engine for a large amount of weight data bandwidth in real time.
