Abstract
PURPOSE: To increase the utilizing efficiency of the buffer, by sectioning the data buffer for transfer of the input and output channel.
CONSTITUTION: The data buffer 2 tentatively storing the transfer data between the input and output unit 1 and the upper rank unit is sectioned to the storage region corresponding to the transfer ability of the unit 1 connected to the input and output channel sections 110 to 112, 210 to 212, 310 to 312, and 410 to 412, each input and output channel section has address register and capacity register, and the control circuits 111, 211, 311, and 411 forms the data trasnfer request signal so that transfer is made by using the storage region allocated depending on the content of the capacity register, and it delivers the address signal and the transfer request signal accesing the buffer 2 to the common sections 1, 3 to 5. Further, the priority circuit 5 determines the priority of the transfer request and the control circuit 4 stores and reads out the data to the buffer 2.
