ABSTRACT:
A variable-length code decoding apparatus for decoding sequential variable-length codewords includes a first barrel shifter for producing a first window output sequence in response to a window control signal, a second barrel shifter for producing a second window output sequence and a code value in response to a decoded codeword length, a relay circuit for latching the second window output sequence for the clock cycle and providing the latched second window output sequence as a decoding output sequence, a first look-up table memory for producing the decoded codeword length in response to a pre.sub.-- fix code of the variable-length codeword that begins at the first bit position of the decoding output sequence, a second look-up table memory for producing a fixed-length word in response to the decoded codeword length and the code value, and an accumulation block for producing the window control signal.
