Abstract
PURPOSE:To increase the transfer efficiency, by installing a write size setting register, a write permission size register and a comparator and eliminating the retransmission caused by the difference of transfer speeds between the input and the output. CONSTITUTION:The same address is set to a write address register 10 and a read address register 30 of a storage device M' in an initial mode. At the same time, the write permission maximum size K is set to a write permission size register 6. The size K is coincident with the memory capacity of a temporary data storage part 2. An external device D' sets the write size showing the number of data included in transfer data to a write size setting register 7 before storing temporarily the transfer data into the part 2. The comparison is inhibited during the writing of the data, and this inhibition is canceled when the data is read. Then the comparison is carried out every time the data equivalent to a unit is delivered. Thus the queuing time is reduced when the transfer data is given to the part 2.
