Abstract
New and improved variable length decoding methods and apparatus. The present invention provides speed performance and efficiency for decoding data by comparing, in parallel, a first plurality of code words of received data with respective values from a code length table. If the compared first plurality of code words are outside of a criterion, a second plurality of code words of received data are compared with respective values from the code length table. If one of the code words from one of the first and the second compared plurality of code words meets the criterion, it is determined which one of the code words from the first and the second compared plurality of code words has met the criterion. Once the code word meeting the criterion is determined, its symbol value is provided.
