Abstract

PURPOSE: To execute the tranfer processing at a high speed, by sending the number of transferable data and the number of receivable data through the data line from both the equipments, making fewer number of them a transfer unit, and transferring it without waiting for a response of the tag line.
CONSTITUTION: When the equipment 1 enters the transfer operation, the tag line 110 is set to 1 by setting the transferable data amount to the data line 112, and also the tag line 114 is set to 1 by setting the transfer data to the data line 116. When rise of the tag line 110 has been detected, the equipment 2 sets the receivable data amount to the data line 113 by the idle state of the data buffer in its own equipment, the residual value of the transfer byte count, etc., inputs the transfer data of the data line 116, and after that, sets the tag line 111 to 1, and responds to the equipment 1. The equipment 1 makes the tag line "0", inputs a data on the data line 113, compares the value sent to the data line 112 with the value sent by the data line 113, makes its smaller value a count value of the transfer unit, sets the transfer data to the data line 116, and continues to transfer without waiting for a response from the equipment 2.
