Abstract
According to one embodiment, a code table generation device includes a frequency table generation unit, a frequency sorting unit, and a Huffman tree generation unit. The frequency table generation unit generates a frequency table including entries each including a symbol and a frequency of occurrence, based on a frequency of occurrence for each symbol of input symbols. The frequency sorting unit sorts the entries in the frequency table by frequency of occurrence. The Huffman tree generation unit generates a Huffman tree having leaf nodes by using a queue that includes storage areas in which the sorted entries are respectively stored as the leaf nodes in an initial state, in response to the entries having been sorted.
