Abstract
A compression unit compresses original data in block units and encodes compressed data, and it generates continuation flag information expressive of the block length of the compressed data at the top part of the compressed data stored in a storage unit. An expansion unit determines the block length of the remaining data of the compressed data on the basis of the continuation flag information, fetches the remaining data from the storage unit and restores the original data.
