Abstract
The disclosure describes a data compression method and a data decompression device corresponding thereto. Firstly, the first frequencies of occurrence of different original codewords are calculated, wherein each original codeword has at least two sub-words and each sub-word has at least one bit. Then, each original codeword is decomposed into sub-words. Based on the first frequencies, the second frequencies of occurrence of all different sub-words are calculated. Variable-length encoding is performed on all different sub-words in a compression manner to generate different compression codes corresponding to all different sub-words. Finally, based on the corresponding relationship between the compression codes and all different sub-words, the original codewords are converted into encoded codewords. Besides, before performing variable-length encoding on the sub-words, the sub-words of the original codewords may be recoded.
