Decompression method and device

The invention relates to the technical field of decompression, in particular to a decompression method and device. In order to solve the problem of high hardware resource overhead of an existing decompression circuit, the invention provides a decompression method which comprises the following steps: acquiring pre-stored to-be-decompressed data, and pre-storing the to-be-decompressed data in a preprocessing buffer unit; obtaining a prefix code from the to-be-decompressed data, decoding the prefix code to obtain first data and second data, the first data controlling a sending mode of the decompressed data, and the second data being used for controlling a data sending amount of the decompressed data; and controlling a sending process of the decompressed data according to the first data and the second data. By utilizing the decompression method and device, the problem of high hardware resource overhead of the decompression circuit can be effectively improved. 本发明涉及解压缩技术领域，具体涉及一种解压缩方法和装置。为了解决现有解压缩电路硬件资源开销大的问题，本发明提
