Abstract
A variable length decoding device for decoding variable length coding data and run length coding data according to the present invention comprises a variable length decoding unitfor serially decoding the variable length coding data and the run length coding data inputted from outside in a state in which 'RUN' representing number of '0' and “LEVEL” representing a magnitude of a coefficient value are combined, a data bufferfor storing the “LEVEL”, address retainersandfor retaining an address of the “LEVEL” corresponding to the “RUN” based on the number of “0” indicated by the “RUN”, a write control unitfor writing the “LEVEL” in the data bufferbased on the information of the address retainers, and a read control unitfor reading the “LEVEL” from the data bufferbased on the information of the address retainers.
