Abstract

PURPOSE:To improve circuit processing efficiency by providing the 1st buffer, the 2nd buffer which has greater capacity, a processor, etc., to a data transfer controlling system which controls transmitted and received data by a circuit controller. CONSTITUTION:When an instruction code, e.g., c3 is sent from a processor 1 to a terminal equipment 9, a processing part 6 stores the code c3 in a buffer b3 and then sends it from a transmission part 8 to the equipment 9. When buffers B1-Bm are used in transmitting an instruction c2 and data d2 by the processor 1, the instruction c2 is stored in a buffer b2. Then when the procesing part 6 detects the buffer B2 being empty, the data d2 of a main storage device is stored in the buffer B2 and the instruction c2 is transferred to the buffer B2. The processing part 6 sends the instruction c2 and data d2 to the equipment 9 through the transmission part 8. On the other hand, when circuit information from the equipment is present, a circuit controller 4 discriminates the information and when it is an instruction code c1, transfer from the buffer B1 to the buffer b1 is performed.
