PURPOSE: To attain operation speed included in output data speed by allowing a pointer generation means to read out localizer information directly from an access mechanism means. CONSTITUTION: A large part, especially blocks 50, 52, 54, 56, 60, of an architecture array is driven by K-bit route width. The value of K is determined by the maximum length of a decoded data segment. A stand-by processor 44 for receiving an encoded segment and repeatedly driving a succeeding state through a retro-coupler 45 calculates the length of each encoded segment and stores the calculated length in an FIFO 50 together with the encoded segment. The processor 44 has a fixed input speed and variable output speed. A don't-care-bit position indicating selection to be executed in the case of merging a large new code word into a small new code word is used for the reduction of the size of an FIFO buffer. |
