Whether a header information processor (101) quickly enters a program inactive state at the timing when it issues an operation start command of an encoding process for a predetermined processing unit to a variable-length code encoder (102), or said header information processor enters the program inactive state upon completion of execution steps to be processed is adaptively selected in accordance with the number of execution steps. One memory (110) is shared by said header information processor and variable-length code encoder, and address input permission means for controlling to grant permission of an address input to the memory to one of said header information processor and said variable-length code encoder is provided. The memory is used as a work area of said header information processor, and as a storage area of a variable-length code table which is looked up by said variable-length code encoder.
