ABSTRACT:
A decompressing method for generally providing more than four bits of decompressed data in each clock cycle. The decompressing method of this invention is capable of decoding four non-long horizontal codes in parallel and selecting either the decompressed data of the first code if it generates four or more bits of decompressed data or selecting the decompressed data of the first code with a combination of the decompressed data of the following codes if the first code generates less than four bits of decompressed data. The decompressing method decompresses the long horizontal codes (codes which generate more than four bits of data) separately.
