A method and apparatus for decoding JPEG Huffman symbols are described. A content addressable memory module stores bit patterns representing Huffman symbols that must be decoded in a single decoding cycle. A compare-add module stores bit patterns representing Huffman symbols that can be decoded in following cycles. The content addressable memory module and the compare-add module each compare a Huffman symbol with their stored bit patterns and generate a corresponding bit pattern when a match is found. The method takes advantage of the high speed possible with a content addressable memory and the small size of the compare-add module. |
