Abstract

A variable length decoder for decoding a variable length code. The variable length decoder includes a first look-up table for receiving and decoding the most significant bits of the variable length code and for producing a first decoded code corresponding to the most significant bits. The first look-up table means also for outputs a conversion signal. In addition, a second look-up table is provided for receiving and decoding the least significant bits and for producing a second decoded code corresponding to the least significant bits. The first look-up table and the second look-up table decode the most significant bits and the least significant bits at substantially the same time. The decoded output of the look-up tables is provided to a selector. The selector selects the first decoded code or the second decoded code based upon the conversion signal.
