Abstract
PURPOSE: To enable the date transfer between peripheral units without exclusive use of CPU, by providing the data transmission channel between the peripheral units controlled with CPU for input and output operation.
CONSTITUTION: The unit provides the main memory unit 1, CPU2, peripheral units 3 and 4, and data transmission channel 5 enabling the data transfer between the peripheral units 3 and 4. The data transmission channel 5 is connected with the peripheral units 3, 4 through the data line 7 and status line 8 and with the CPU2 through the input and output line 13. The data transmission channel 5 is started with the instruction from CPU2 and data transfer is started. The data transmission channel controls the data transfer between the peripheral units 3 and 4 without via the main memory unit 1 without the instruction of CPU2 when start is made once from CPU2.
