PURPOSE:To facilitate data transfer from the auxiliary storage device to a data processor. CONSTITUTION:A pulse signal is supplied from the side of the data processor through a line L1. With this pulse signal, a counter 12, a memory 11, and a multiplexer 13 are powered ON. The counter 12 counts the pulse signal and supplies its counted value as a read address to a memory 11. The low-order three bits of the counted value are connected to the multiplexer 13. Data read out of the memory 11 by the multiplexer 13 in parallel according to the counted value are sent out of the multiplexer 13, bit by bit, to an output line L2 and inputted to the data processor. |
