Abstract
PURPOSE:To ensure the smooth transfer of data even in case the transfer interval among devices is smaller than the maximum allowable time of occupancy, by using two first-in/first-out buffer memories. CONSTITUTION:When a transfer data is read out of a floppy disk, the data is successively stored in the 1st buffer memory 11. When the occupancy of a common bus 6 is released, the signal is applied to the buffer 11 by a direct memory access controller 14. Then the stored data are delivered in a first-in/first-out way. In case a data is transferred to write the data into the floppy disk from a main memory 2, the data transferred from the memory 2 is stored once in the 2nd buffer memory 12 via the memory 2 and the bus 6. A transfer controller 13 feeds the data stored in the memory 12 to a floppy disk controller 8.
