Abstract
PURPOSE:To smooth the data transmission by using a CPU so as to control data transmission/reception between a main bus and a sub bus and saving a data into a buffer memory under the control of the CPU at the stop of data caused by the difference from the transmission speeds of the data between both the buses so as to eliminate the congestion of data in each interface. CONSTITUTION:An interface unit 2 is connected to a main bus 1 having a specific address and an interface unit 4 is connected to a sub bus 3 having a different transmission speed and transmission system from those of the bus 1. The relay control of the handshake of data transmission/reception between both the buses 1, 2 is controlled by a CPU section 3. Then a data is saved in a buffer memory 6 based on the control of the CPU section 3 at the stop of data caused due to the difference from the transmission speed between both the buses 1, 2. Then the CPU section returns an ACK signal without fail in case of the handshake so as to avoid the congestion of data in the units 2, 4 thereby smoothing the data transmission.
