Abstract
PURPOSE: To send the information quickly in independent transfer mode, by performing the address write-in and data read-out from the processing unit to the memory unit by the first transmission systems, and performing them from the processor to the memory unit with the second transmission system.
CONSTITUTION: The transmission system 31 transmits the address information representing the write-in address from the address register 21 of the processor 2 to the address register 11 of the unit 31 when the address information is written in the memory unit 1. Further, the write-in data is fed to the write-in data register 13 of the unit 1 from the write-in data register 23 of the unit 2 via the transmission system 32. On the other hand, when the data is read out from the unit 1, after the address information representing the read-out address is fed from the register 12 of the unit 1 to the register 22 of the unit 2, the read-out data is transmitted from the register 12 of the unit 1 to the register 22 of the unit 2 via the transmission system 31. Thus, the transmission system is not expanded between the units 1 and 2, allowing to transfer the information quickly in the independent transfer mode.
