Abstract
A flag indicating whether a decoding process is completed or continued is disposed in each of entries of a decoding process table. A decoded value and a significant bit length are recorded in the entry of a decoding process completion. Information for identifying the decoding process table which is used in a subsequent process, and a bit length that is clipped from a code word which is used when referring to a subsequent table are recorded in the entry of the decoding process continuation. When the decoding process starts, the information for identifying the table to be used and the bit length that is referred to from the code word when referring to the table are designated together with the code word. The decoding process table reference is repeated as the occasion demands. With the above configuration, there is provided a variable length code decoding device.
