Abstract
PURPOSE: To increase the efficiency of computer usage, by reducing the data transfer time at computers so that the data transfer can always be available when the opposing computer is available for reception of interruption.
CONSTITUTION: CPU1, CPU2 incorporated in the microcomputers MC1, MC2 respectively are connected with a plurality of data buses B0WB11, and on the way of the buses B0WB11, the buffer registers BR1, BR2 are inserted so that the input side is anti-parallel. Further, when write-in instruction WS1 is given to the control terminal C1 with the register BR1, the data stored in the general register GR1 incorporated in CPU1 is written in via the buses B0WB11, and when readout instruction RS1 is given to the control terminal E1, the data written in the itself is transferred to the general register RG2 incorporated in CPU2 via the buses B0WB11, and when the write-in for itself is finished, output is delivered to the control terminal X1 to give interruption to CPU2 via monostable multivibrator OS1.
