ABSTRACT:
A variable-length decoder arrangement having enhanced speed capacity, in which an input bit stream is tagged with the codeword boundary information by a tree searching state machine positioned in front of a tag buffer. This codeword boundary information, after having been windowed in a barrel shifter, is applied to a simple codeword-type-independent look-up table decoder coupled to an accumulator for generating the window shifting control signals for the above barrel shifter and for a barrel shifter receiving the codewords in the decoding section of the variable-length decoder. The enhanced speed is achieved by reducing the complexity and, therefore, the propagation delays of a length decoder, or eliminating it altogether.
