Abstract
PURPOSE: To speed up the input and output interface operation, by taking the specific field of the instruction word read out from the memory address as the transmission signal pattern and by controlling the input and output interface operation.
CONSTITUTION: The instruction read out from the memory 5 is stored in the instruction register 3, the instruction format field 3-1 is interpreted in the decode circuit 6, and the content of the reception signal latch circuit 1 is set to the memory address register 4. That is, the memory address accessed next is determined with the reception signal pattern of the circuit 1, the content of the memory 5 corresponding to the memory address is read out newly and is stored in the register 3. At this time, the transmission signal pattern corresponding to the reception signal pattern is stored to the input tag field 3-5 of the register 3, the field 3-1 is interpreted in the circuit 6, and the content of the field 3-5 is transferred to the circuit 2 by instructing the content of the field 3 to the transmission latch circuit 2 to be stored, and it is delivered to the opposing unit
