PURPOSE:To output all data to a processing section even when a compressed data is processed in the unit of blocks. CONSTITUTION:When data transfer is finished and a data quantity of a memory 21 is a prescribed value Y(512 bytes) or below, a data is transferred by the prescribed value Y from a host computer 1 excessively or a data is outputted from a system control section 25. Thus, a difference between both counts of a write counter 22 and a read counter 24 is 512 or below and all compressed data are transferred to an expansion processing section 5. Moreover, a data is outputted by enabling a data output available signal forcibly. |
