Abstract

The embodiment of the invention provides a data compression method, a decompression method, an apparatus and an electronic device. The method calculates a first offset between a head address and a reference address of an N-th data section. The first offset is added to a data header, wherein the data header sequentially arranges the offset of each data segment, and N is a natural number. As the offset of each data segment is recorded in the data header, the data segment can be read at the same time and processed in parallel by the offset, thereby improving the data processing efficiency.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a data compression method, decompression method, device and electronic equipment. Background technique [0002] In the process of data storage, compressed data is usually stored in a bit-by-bit storage format. For data 5, the context may decide to use 3 bits to store it, and the stored bit value is 101 at this time; the context may also decide to use 4 bits to store it, and the stored bit value is 0101 at this time. The smallest storage unit of a current storage device is usually a byte (8 bits). Therefore, when data is stored, the bit data needs to be spliced ​​to form byte data for data storage. For example, the bit data to be stored for two adjacent data 4 and 5 are respectively 0100 and 0101, then these two bit data are spliced ​​into one byte 01010100 and stored. For another example, the bit data that needs to be stored in the adjacent two data 5 and 6 are 00101 and 0011...
