<p>PROBLEM TO BE SOLVED: To provide a the huffman coder that outputs a plurality of coding factors included in a huffman code table in the order of frequency of generation regardless of a small storage capacity and successively outputs the frequency of generation corresponding to the coding factor received sequentially. SOLUTION: A huffman RAM 3 stores frequency of generation to an address denoted by each coding factor as data. A frequency of generation counter 4 outputs the frequency of generation as a count. An address counter 7 outputs a coding factor as a count and gives the count to the huffman RAM 3 as an address. A coincidence detection circuit 5 compares an output of the huffman RAM 3 with the count of the frequency of generation counter 4. The address counter 7 is incremented till the coincidence detection circuit 5 outputs an agreement signal MT. A count of the address counter 7 is outputted as a coding factor when the agreement detection circuit 5 outputs the agreement signal MT and the frequency of generation counter 4 is incremented.</p> |
