Transfer system for transmission and reception data of transmitter

Abstract

Abstract PURPOSE:To improve the processing capacity of a data transmitter by transferring the transmission/reception data between a transmission controller and a transmission/reception buffer memory via a data transmission exclusive bus and transmitting the information between a computer and the transmission controller or a terminal device. CONSTITUTION:A transmission controller 4 is connected to a local bus 5 via a bus control multiplexer 11<1>, and at the same time transmission/reception buffer memories 61, 62, 71 and 72 are also connected to the bus 5 via multiplexers 112 and 113. A transfer data transmission exclusive bus 12 is provided among these multiplexers 111-113 in addition to the bus 5. The switching is performed by these multiplexers to transfer data between the controller 4 and the transmission/reception buffer memories via the bus 12. While the information is transferred between a computer 10 and the controller 4 or a terminal device 8 via the bus 5.
