Abstract
A Huffman code decoding circuit including a leading bit position determination unit for determining a leading bit position of a Huffman code to be taken out of a Huffman code data sequence to take in a predetermined number of bits from the leading bit position of the Huffman code data sequence, a first decoding table for inputting a first data sequence composed of a predetermined number of bits staring with the leading bit of the Huffman code data sequence output from the leading bit position determination unit to output a first decoded word and a first code length corresponding to the first data sequence input as an address, a plurality of 2nd to n-th decoding tables for inputting 2nd to n-th data sequences composed of a predetermined number of bits starting at a different bit position of the Huffman code data sequence output from the leading bit position determination unit to output a decoded word and a code length corresponding to the 2nd to n-th data sequences input as addresses, and a selector for selecting one of the outputs of the 2nd to n-th decoding tables in response to the first code length output from the first decoding table as a select signal to output a second decoded word and a second code length.
