Improved variable code length decoder is disclosed, including a storage part for temporary storage and production of an encoded code word in response to a read signal, a switching part for selective production of the code words from the storage part in response to a switching signal, a barrel shifter for shifting a decoding output window thereon in response to a shift signal in producing a predetermined number of bits of the code word from the switching part for decoding, a storage part for temporary storage and production of the code word from the barrel shifter, a table for producing a decoded code word and a bit length of the code word of the predetermined number of bits stored in the storage part, and a control signal generating part for using the bit length of a code word at the present clock received from the table in generating the switching signal, the shift signal and the read signal.

[ What is claimed is:] [1.] A variable length code decoder comprising:a first storage part for temporarily storing and producing at least one encoded code word in response to a read signal;a switching part for selectively producing a word in response to a switching signal based on the at least one encoded code word produced by the storage part;a barrel shifter for shifting a decoding output window in response to a shift signal and for producing a predetermined number of bits of the code word produced by the switching part based on the shifted decoding output window;a second storage part for temporarily storing and producing the code word produced by the barrel shifter;a table for producing a decoded code word based on the predetermined number of bits stored in the second storage part. and for producing a bit length of the decoded code word; anda control signal generating part for generating the switching signal, the shift signal and the read signal based on the bit length of a decoded code word at the present clock received from the table, the control signal generating part including an adder for adding a bit length of a current decoded code word and previously decoded code words to produce a shift signal and a carry signal, and a latch for storing the carry signal and for producing the storage carry signal and a read signal.
