Abstract
PURPOSE: To increase the processing ability, by constituting the system that the control processing to perform the data delivery to the line terminal unit and the data write-in operation to the buffer memory is made one machine cycle.
CONSTITUTION: The data from the data channel unit DCH is inputted to the input and output data buffer 200. The logical operation section 201 makes the address on the buffer memory 203 to store the said data in one machine cycle. In the next one machine cycle, the logical operation secion 201 takes the reception data from the buffer 200 and inputs it to the data buffer 204. The buffer mrmory 203 stores the content to the designated address in the next machine cycle. In case of data delivery, the logical operation section 201 reads out data from the buffer memory, performs logical operation and the result is inputted to the data buffer. The line contol secion 205 initiates transmission in the next machine cycle. When the delivery operation is executed independently of the microprogram, the transmission can be made by one machine cycle.
