Abstract
According to one embodiment, a data compression device includes all-literal determination circuitry and end-of-block symbol addition circuitry. In a case where dictionary-based compression on a first data block is performed, the all-literal determination circuitry determines whether all one or more symbols in a second data block are literal symbols. The symbols are obtained by performing the dictionary-based compression on the first data block. When all the symbols are literal symbols, end-of-block symbol addition circuitry does not add an end-of-block symbol to an end of the second data block. When at least one symbol among the symbols is not a literal symbol, the end-of-block symbol addition circuitry adds the end-of-block symbol to the end of the second data block.
