Abstract
A method for processing data overflow in a decompression process, includes: decompressing an original text, and detecting whether a data overflow event occurs in the decompression process; in response to detecting the data overflow event, storing first data obtained by decompression in a host cache into a target memory, and closing a data read-in port of a decoding engine; decompressing data which is being decompressed in the decoding engine to obtain second data, and storing the second data into a cache of the decoding engine; calculating a position of the decompressed data in the original text; obtaining, on the basis of the position, data which is not decompressed in the original text, re-decompressing the data which is not decompressed to obtain third data, and storing the second data into the target memory; and splicing the first data, the second data, and the third data to obtain complete decompressed data.
