PURPOSE:To reduce a control device of an information processing system, by controlling the final data by a transfer end signal, in case of reading out a recording data of a device whose recorded data length is unknown. CONSTITUTION:When a device whose data length is unknown, such as a magnettic disk device is connected to a terminal (a), a pulse is sent out from a flip flop 14 by a normal end or check end signal, and the final byte of a read-out data inputted to a buffer register 10 by the final think-in signal is sent to a buffer register 12. At the same time, a data setting movement controlling circuit 15 moves a data toward 4 byte shift registers BF1-BF3 even if data of 4 byte portion are not collected in a 4 byte shift register BFO, and starts its transfer end operation. |
